So this may sound silly. I (19F) posted about how my girlfriend (18F) doesn't see a future with me and instead is planning to marry a guy. She also may have biological children in the future and talks about it sometimes. Now, part of it is because her family will apparently hate her if she ever marries/has a long-term relationship with a woman, but the other half, I'm not too sure. Yesterday when we saw each other and we were hanging out with our aroace friend (almost 21NB), my girlfriend says she's had crushes on women and men, so she considers herself bisexual, but she also talks about her crushes on women in the past and stuff and says "I don't know if I actually saw them as more than a friend".
I probably shouldn't feel insecure, but given everything she's talked about, I feel like she might see me as just a friend and just THOUGHT she liked me but she continues to date me, so I don't know. Liking men and all, she hardly talks about attractive women either as she doesn't know if she has crushes on them and she usually talks about attractive men and stuff.
It very much sounds like you were already just friends.
