I'm really going to try to not make this into a wall of text.

We've been bf/gf for a little over a month but were FWB for 3 months. I know it's a bit fast for the "I love you" and stuff but based on my previous.....anyways I really feel it when she says it.

While we were FWB she would always jokingly say she would teach me some moves (She's my first...yea i know) that I could use on someone else (she was still in a relationship...again I know, in my defense she was very unhappy and only stayed bc of her kids and she "gave up hope of ever being happy again", her past is unfortunately littered with abuse and her previous long term relationship was more of the same.)

I'm no stranger to depression or feelings of inadequacy. Instead of trying to "fix" her negative talk about herself and life I let her know that I am there to listen and provide her with support while she goes through what she is going through....I mean I can't and won't just say, "get over it, ugh just stop complaining, it's easy to fix this see...."

Anyways, if i say something like, "I miss you, I want to see you, you make me so calm(big one for me) etc." She usually responds with, "why?" My response is..."What do you mean why do I miss you? because i fucking love you and haven't seen you in a bit"

She's asked me on multiple occasions whether or not I am sure I want to continue our relationship because she feels like she is a burden and I shouldn't have to deal with her, this is from last night, "I know I upset you, maybe you should really think about if you want to be with me. I'm a fucking stupid retard that says tupid shit, i hope you think about it, i love you and will always love you but I know when I am becoming a problem."(sic)

Without getting into the various issues she's dealing with, (main one is her ex trying to keep her from her kids) she thinks this is bothering me. On countless occasions i keep saying it won't always be this way, yes right now this sucks, she's overwhelmed and etc. but im with her and support her...It works for a certain period then back to her saying i deserve better.

Well I failed at not doing a wall but whatever. I genuinely love this woman she is my friend and she is the only one I have ever known to make my anxiety go away just by being with her.

I don't think this is a deal breaker but I would just like some advice on how others have dealt with this.

Fun fact and basically the reason why her last text (quoted from above) bothered me...I told her I wanted to express how I was feeling about her, I gave her oral which left her with the inability to form a sentence for some time....then after I leave she says I shouldn't have to deal with her.

tl;dr gf says she loves me, yet still says I deserve better and should find someone who is not a, "fucking stupid retard that says stupid shit."

P.S. thank you in advance.
