Am I overthinking this

M27 and my girlfriend F25 have been dating for 4 months.

Things started off amazing, we’ve pretty much seen each other most days as we live in the same city and can catch up really easily. We’ve gotten really close over these months and we’ve been talking long term and our future together. I think I’m getting to the stage where I can say I love her.

However 2 things have happened recently which have worried me. My GF has a terrible relationship with her parents (like awful), they have verbally and physically abused her most of her childhood. I on the other hand have grown up in a loving family which I’ve been so blessed with. The problem is, I’ve noticed recently that my GF is becoming controlling over when I visit my family and she always wants to come with me , because we’re a ‘team’, which doesn’t bother me however something happened last week. My Grandad recently died and my mother text me saying my dad misses me and asked me to come home (they live like 30 mins away) and spend some time with my Dad (who’s father has died). So I told my girlfriend what my mother said and she got really annoyed at my mother and said that my mother shouldn’t of said that and that she’s guilt tripping me into going home to see them??? I then told my GF that I wanted to go and spend an evening with my Dad and she got really upset that I suggested that I would go without her! I consoled my gf and told her I wouldn’t go without her.

It feels like she’s transferring/projecting her relationship with her parents onto my relationship with my parents. What do I do?
