Me (20) and my fiance (18) of 3 years are...moving into the trouble stage. Little young I know, but just listen. I just need help to get her to listen to what *i* want. Heres the background. [apologies ahead for spelling and errors, its late and i have to type this while shes sleeping...so she doesnt overreact]

I am a quiet guy around new people, but after i get to know you, I get more involved. She suffers from extreme low self-esteem, anxiety, depression, attemped suicide multiple times, just a whole beautiful mess. I always fear that my choices might set her over the edge. as she overreacts veryyyy quickly/

I met her in high school, me a junior she a freshmen. She looked older then what she is, and after some heehawing around we finally got together. It was great. As high school relationships go, it was tough getting time. But as our relationship strengthened, we had more and more time together. About just under 2 years into it, we found out she was pregnant. (yes, i already got the whole spiel about "being too young" and "not ready yet", please dont say anything about it. On our 2 year anniversary, I proposed to her. I love her with everything I have, and I always have and always will. After she said yes, things changed. Alot. First, we started being together ALOT more. It was something like every other day after school, and either saturday or sunday for the full day every weekend. Then it was every day after school, and the full weekend unless it was a family thing that kept us apart. I didnt mind, as my time with her was amazing. Then the issues arrived:
1. I love video games, and up to this point i kept myself limited to when she wasnt over, because i didnt want to be rude. After a few weeks of not having any time, I wanted to play with da boys again. She didnt "throw a fit" per se, but she was grouchy and short with me for the rest of the day. Turns out her father basically ignored her when she was younger, instead more focused on his call of duty then on his 3 daughters. After i learned that, I went back to not playing. Now that im living with her (reason to be explained later on) I ask her if i can, she gets grouchy and short, ignores, whatever she can do to make me feel bad without being physical. Im not asking every day, just an hour or 2 every now and again. Instead, I have to give up my sleep time on weekend nights (and nights where i have off the next day) to get my time in, without having and consequences.

1. Our son (We named him Gerald, after my dads dad) died in her womb at 23 weeks and 5 days. It was a hard first week, but i am not one to dwell on the past. I hid my tears, cried where i was alone or unseen. Called off work for a week, but someone has to pay the bills. Shes better now, but for the first 6 months after he died, she kept accusing me of being "glad that hes gone, " claiming that his death didnt affect me as much as it did to her, that i didnt feel as bed as she did,and could never, as she was the mother and he was inside of her. It hurt me, but I knew that she was hurting too. So i kept my mouth shut. Truth is, I dont know what to think. Hell yes I want to be a dad. Hell yes I was looking forward to it. But we werent near ready, no money saved up, living with her mom, my being the only source of income. I like to think that hes better in heaven, then with parents who still dont know each other 100 percent, and who arent ready.

2. She wants to try again. Not even 6 weeks after Geralds death she was talking about the next one. I keep pushing the arguement that yes we may *want* one, but we *need* to wait. She just assumes that i dont want a kid, that i dont care what she says.

3. She says she trusts me, but not other woman. She says that she knows i wont pursue other women, and that she can trust me that i wont talk to random women, but she doesnt trust other women, that they wont pursue me. I said "so what if they pursue me, you are the one who has me. They will never have me." Shes afraid that i will say yes to them, but she trusts me to not instigate? She used to go through my phone (snapchat, facebook, internent history, whatever "other women could contact me through") and on my computer, and if she found anything she didnt like she would blow it out of proportion, and would get even angrier when i showed her that it was a ad for such and such, or my friend would send me links to roblox porn on pornhub, cause thats what guys do. She has since stopped going through my phone, after i had a very long argument with her about the real meaning of trust, (within my knowledge anyways), but whenever i get a notification its always followed with "whos blowing up your phone" even if its just 1 dink from reddit after hours of silence.

4. She gets extremely irritated whenever i say no, or good plans change. I am not a money man, but whenever i have it, i usually spend it on her. I got her a car (dad said "i dont have any money, then spends 100s of dollars in a weekend at Gettysburg") I got her 2 phones (she has an amazing habit of breaking phones) I get her whatever food, makeup, candy, whatever she wants. After we moved it, i wanted to start saving a bit, and buying my self stuff. I cant take her to the store with me, because it always turns into "oh look, this is cool" grabs it, looks it at for a very long time, then sulkingly puts it back, and is grouchy for some time after that. Or even this weekend. My birthday was yesterday, and i told her that we could get a weekend at a hotel for....fun purposes (her mother doesnt allow it in her house, which i respect). i had an unexpected 200 brake repair on HER car, and therefore can only get the room for 1 night, plenty of time for us to burn off all the sexual energy we have pent up. She was apparently looking forward to having that weekend of sleeping with me ( i sleep on the couch downstairs, her in her room upstairs) and this change of plans she didnt like. She immediately started calling her friends, saying that our plans were canceled and that we needed a place to stay for a night, to make me feel bad. We finally settled, but thats how she is to everything i say, or promise but cant keep even if i tried (which i try for all of them) that she doesnt like.

This aint even scratching the surface for whats wrong, but im too tired to think of anything else/ If you got the far, thank you for taking the time. To be clear, I have no REAL intentions of leaving her, not just for the sake of her mental wellbeing but mine as well. I love her, and i would do anything for her. I just want to know whats right and wrong for what im doing, or not doing. Any help would be great. Thank you
