Almost two years together with my partner and I still am not comfortable with her being friends with her ex. We have discussed this topic a few times before, ending up kind of talking in cricles each time. The basis of my problem is that I dont like that they hangout by themselves, since they are both a part of the same childhood friend group I would never make them choose between a relationship and that.. which is why Im afraid Ill just have to put my foot down and break up with her after yesterday: going to your ex's place by yourself and hanging out for the day because he is "sad he got broken up with" by some girl he had been seeing recently. Red flags are shooting off in my brain but I dont want to seem controlling or crazy.
