So my dad asked me to go on a trip with him for a weekend to go to fenway park (something we have always talked about doing) but my gf doesn’t like that I’m going. Now I’m having a hard time talking to her because she is so upset she is just being dry with me. And I have been okay with her going out of town for a few weeks in the past but she’s not okay with 1 weekend with my dad none the less. So I just don’t know what I should really do. I’m worried that this could only be the beginning of things getting worse. I love her and I always tell her but she just seems to be so insecure about me doing stuff without her.
TL;DR should I stay with someone who gets mad at me for wanting to go on a weekend trip with my dad?
