My boyfriend (M19) invited his female friend to a family trip 15 minutes away from my (F19) house
My boyfriend and I have been together for almost 6 months now, we got together at the university we both attend and would see each other all the time because we lived on campus. Since it is now summer break we're currently 3/4 hours away from each other, that being said my boyfriend is coming into my town to visit the beaches with his family. When he told me this, he explained that he had invited his female friend to go with him because he wanted company and asked if I was okay with this, and further stated that depending on my answer he would uninvite her. I told him that the scenario made me a uncomfortable and that I wasn't okay with it.
He got confused and upset at that, and starting saying he just wanted company considering that all his male friends are busy, he additionally brought up a past argument (where we got into a fight about parties and how he wasn't comfortable about me going to parties in revealing clothes, this was resolved with him saying he was okay with it) and that how since he was okay with certain things its unfair that I'm not okay with this.
I told him that I would be okay with her being invited if I was invited as well considering it's only a few minutes from my house and I'm not busy. He said that he doesn't want his parents to know that he has a girlfriend because their very controlling and would give him shit for it. I said I would be okay if he could at least meet up with me or visit me then, considering we won't see each other until September, he said his parents wouldn't allow that either. He's now upset at me for this and I'm upset and confuse as well, considering the female friend is not someone he's extremely close with and the fact that he likes to be alone most times.
Also note, just to add a bit of perspective, I've asked to meet up and visit during the summer before and he's shot me down using his parents as an excuse all the time.
Is there another perspective I should look at?
