I have been with my girlfriend for almost 3 years. Things were great so we decided to move in together. About a year and a half ago we were on a road trip from Colorado to Maryland to visit her mother. We stopped at a gas station and she went in to use the restroom. While I was sitting there a Facebook message popped up. Being curious, I opened the thread and seen that she was sexting with another guy. I closed it and immediately got sick to my stomach. She came out and asked what was wrong. So I told her. She started crying and apologizing. We were so far from home that I just continued to her mom's house because I didn't want to ruin the vacation for my daughter. After we got back, we worked on things and they got better. Over the next year I ended up working quite a bit of overtime. But things were going pretty well there was a lot of love between us. So we decided to buy a house together. After going through the process and pain of finding the house and getting the mortgage loan we were finally set. I made the down payment. The next day we were getting ready to do something and she left her phone on the bed. I looked in her phone and the same guy was sending her porn. She walked in the room and got mad that I looked in her phone. I asked wtf was going on and she didn't know how he got unblocked. She talked me down off the ledge and we ended up signing the contract 2 days later. Things seemed to go back to normal for the next couple months. We were moved in and making the house a home. About a month ago she started getting a little bit more irritable and my constant worry probably didn't help. We had a big argument on Thanksgiving and I brought up the guy texting and it got pretty heated. I explained to her that I didn't feel like I was getting enough affection and she said that it was because I wasn't being her partner and she was doing too much around the house without my help. The argument died down and we ended up watching a movie on the couch cuddling. Over the next couple weeks we had a few more fights but we decided that we wanted to work things out together. So we both went to therapy on our own. I met her after her appointment and we went to dinner. She was super happy and it was like I had my girl back. Then last Monday I realized that she wasn't wearing a necklace that I got her. It had a very special meaning and it was something that she wore everyday for almost 2 years. We argued about it and then went to work. Later I got a notification from life360 (her idea) that she was home. I called her and she said she went home with a migraine. We were texting and she was telling me that she loved me. I asked her if we were okay. She told me that everything was okay she loved me and that we were still together. About an hour later I got a notification that she turned her GPS off. I called and she said that she didn't realize it was off and she was going to get chicken nuggets with the dog. She said she would turn it on when she got to a stop. I waited and called back. I asked what was going on and she said she would turn it on later. I told her that she was manipulating me and she hung up. I was immediately blocked on all social media and calls. I left work to go home and she was gone. All her stuff packed plus essentials for a new place I assume. All I have is a letter that says " I can't do this anymore. My mental health is struggling and this relationship is no longer healthy. I love you very much however we no longer belong together. I will give you until next Monday to switch internet trash and gas into your name. I will reach out in a few months to deal with the mortgage once the dust settles so to speak." I'm going through so many emotions and am absolutely heartbroken. I still want her to come back. I can't afford to keep the house without her. I don't want to live here without her. I want to talk to her but have no way to contact her. I've increased the amount of therapy I'm receiving and trying to fix my flaws. I really just want my family back 😞
