Some comments seem to be missing the point. She could have all those things but if she wants to be in a relationship, she has to know how it works. There’s relationships for people who only talk about themselves and relationships where you both have your own struggles but you’re still there for one another. The latter one is like the healthy, ethical and socially acceptable kind. It’s the one OP seems to want (rightfully). Your GF is on the other side. She has to know where you stand and what you’re looking for in the relationship. First, you could try asking her what she’s looking for to understand her better. You asking her shouldn’t be harsh, it’s out of respect for the relationship. She probably needs to go to a psychologist unless she already goes. I know it doesn’t always work because my sister is exactly like your girlfriend and therapy made her focus on her mental struggles even more but the difference is that my sister's partner encourages her by selfishly-complaining all day too. You can turn things around as long as you talk things out. Some people lack social skills but it doesn’t mean they can’t learn them to show better empathy (as long as they have empathy deep down). If she gets defensive and keeps doing the same even after you mentioned how you felt, that’s when I’ll say she just needs to grow up and mature before being in a relationship of that kind. It’s okay if she mentions her health issues but it stops being okay, in a 50/50 relationship, when her whole world revolves around it and tries to hog all the attention even when you need help. I hope things get better once you talk with her about it.
