My girl (26F) accidentally admitted to only dating me (28M) for financial security. What does it say about me that the only woman I've ever loved only loves me for my money?

My girl has been acting very strangely (and coldly) the last few days. I'm starting to suspect she's found someone else but I have no solid proof. She has a friend coming into town this weekend and they are going out, so I asked her if I could come with? We've all been friends for a while, and she has always been cool with me tagging along to things like this. But this time she wasn't having it. <br><br>When I asked her why she got very defensive and eventually just said "No, I am going to be there with just (Friend's Name) because she just needs someone who cares about her. I love (Friend's Name) very deeply and she's always been good to me and I want to support her during a tough time." And that's fair enough. I responded with "Of course, please go be there for her. You two are great friends and she is lucky to have you." <br><br>But then she said something really shitty. She said "Yeah, I mean, unlike you, (Friend's Name) is actually a good person. Do you remember when we met? I knew that you were a good catch. But you've always been a self-centered asshole and I just accepted that as the price I have to pay to have a good life." <br><br>I was really caught off guard when she said that. I had no idea she thought of me that way. I asked her to explain what she meant and she said that I'm not as good of a person as she is, and I don't care about anyone but myself. And that's why she has to go be there for (Friend's Name). <br><br>I don't really know what to say to that. Honestly it didn't even really bother me. I know I'm not the best person in the world. But it did make me realize I probably don't even really love her. I just really like having her around. We've been together for about 5 years now and I sometimes think about marrying her but I don't feel any deep passion for her. She seems like she's been acting strange lately so I'm wondering if I should just end it. But I've never even had a girlfriend for more than a year at a time, and it feels good to have her around. <br><br>We have a really easy and convenient relationship and we don't fight often. It's mostly been a really happy relationship until recently, but I'm starting to feel like she doesn't even like me. I don't know what to do. We've talked about eventually buying a house together. But now I don't even know if that's what I want. I like not having to worry about money. <br><br>But I don't want to be in a relationship with someone who thinks I'm a bad person. Honestly I've never really given any thought to if I'm a good person or not. I've always thought "why worry about that?" But now I'm starting to wonder. But no matter how hard I try, I just can't seem to think about anything other than money.
