That's actually a good question... At first it was because she wanted her family and I to get to. know each other and feel like part of each others lives. I do get that, that's why I did it for so long.
But tbh she feels the need for us to do everything together. I think she just doesn't like being by herself, especially in situations where she feels like she has to do something she'd rather not actually do. She even has said that if I'm there it's easier for her to leave quicker (which factually isn't true, she leaves way faster if I'm not with her for whatever reason, but that's how she feels I think)
Ahh, that can be annoying. I feel like my gf is like that sometimes as well. But yours shouldn't be feeling that way about meeting her parents though ---
