My girlfriend who was in a wheelchair asked a good looking man if he'd go out with her if she could walk, I want to break up with her

My girlfriend (23f) and I (28m) have been dating for two years, she lost all feeling to her lower body in a bike accident, and I met her in a park where she was waiting for me (it was actually an accident, she was actually waiting for another man she was seeing)<br>She was a lot of fun, it was clear she was going to be disabled forever, I took her under my wing, I was basically her volunteer at first, helping her out with shopping, housework, bathing and more, she needed help with so many different things<br>In the past two years I've helped her get her life together, we were able to get her a great job in tech, she makes a lot more than I do, and I'm mostly able to spend time with her now<br>I don't know how long I managed to avoid falling for her, but it was a long time, but I do love her, she's been a lot of support, it's amazing to see her overcome so many struggles and she's a great person, and a lovely girlfriend<br>But some days it feels like she's never happy, she's so bitter about no longer being able to walk, she lashes out at me and others occasionally, I've learned to be understanding of it, but I've talked to her about it and she just says it's never going to change<br>She has such a low opinion of herself, I'm not sure how much of it is her disability but she thinks she's ugly, even though she's not in my opinion, she doesn't take criticism well, which makes it hard for me to talk to her about things that bother me<br>I'm really at a loss for what to do, yesterday we were at the store getting some groceries, and there was a guy asking her where things were, he was actually working there but she didn't seem to get that, she kept asking him questions and I could tell he was flirting, she was too, and I was okay with it, I know we weren't exclusive but I also wasn't trying to be<br>At one point I went off to find something, and when I came back, she was actually out of her wheelchair and standing on her legs, she wasn't putting any weight on them, she was being held up by this guy who was behind her, and he was essentially holding her up, and she was looking back at him, and kind of flirting<br>I couldn't believe it, at first I thought she was just standing up with his support, but when I got closer, I could see how she was putting her weight on him and looking into his eyes, it was so obvious, and he was caressing her hair<br>She saw me and struggled to get back into her chair, she looked so embarrassed, and honestly a little scared, and she just mumbled something and got away from the guy as fast as she could, and told me to stop staring and let's go<br>As soon as we got home I confronted her, I asked her what she was doing, and she burst into tears and told me she was embarrassed and she could see I was angry and wanted to just go to her room<br>I insisted we talked, she finally admitted she was flirting, and when I asked her if she had ever stood up without any support before, she said no, but that she felt so embarrassed she didn't want to talk about it<br>She went to her room and I stayed in the living room, I was so upset, what she did really bothered me, but I calmed down and went to talk to her, no matter how bad it was, it wasn't time to punish her<br>I told her I was upset, and that I wasn't mad, but that I needed her to explain to me what was going on, and she just cried and said she was embarrassed and would never do it again and that I should forgive her<br>I told her it was okay, even though it wasn't, but I was willing to work through it, I was calm and trying to be understanding, but then she started asking me questions, and it just made everything worse, she asked me if I thought the guy she was flirting with was hot, and I said yeah, he was a good looking guy, and she asked if I thought she was hot, and I said yes, of course, she's attractive to me<br>But then she asked if I would date her if she could walk, and I kind of joked and said "yeah, maybe I'd ask her out even", and she just kind of went quiet, and I could tell she was upset<br>I think what she wanted me to say was that I'd be with her no matter what, but the truth is that it's hard dating someone in a wheelchair, even though I don't think I would want to be with anyone else, it's hard to not think about how difficult it is, and how I don't know if I want to be together for the rest of our lives, I think she wanted me to tell her it was easy, and I don't know why I didn't, no matter how hard it is, I want to be with her, and I want her to know that<br>I tried to talk to her more, but she essentially kicked me out, she told me she was going to sleep and to leave her alone, and when I tried to say something, she told me she just wanted me to leave<br>She's gone to her room to sleep, and I'm in the living room, and it's 3am, I'm so confused, I don't know what to do, and I don't know what she means with that question, I don't know if she's just upset, or angry enough to break up, I don't know if I want to break up, but I don't know if I can just ignore this, I think I'm going to try to talk to her in the morning, but right now, I have no idea what to do
