I am in a woman in her 20s man in their 30s relationship. I know that dynamic. Don't take undue responsibility. Your girlfriend probably knows what she wants. If she is with you to have a caretaker, that's unhealthy but don't feel the need to hover.

For your girlfriend...it sounds like you are both doing a good job trying.... TALK (which you are)... that's all I can say..

For what you mentioned about body stuff, women get more attention but body issues are not uncommon with men, just wondering if there are issues that YOU might be dealing with in this relationship? A therapist might be able to help here your side of the story... always better to talk to a partner but sometimes you just need to unload... good luck
