<human>: I've been seeing this guy for 3 weeks, tonight he was supposed to meet my parents... my ex happen to come around with some of my other friends... we get on ok... so my bf arrives greats everybody and when my ex extends his hand my bf ignores him, he says why is he here? I told him he was just a friend he then asked if he was invited and I told him again he was just a friend then he asked if my ex had any "friends" there when he met my parents... then he left... I tried to talk to him outside and he told me I "belittled" his opinion which is why I find him leaving extreme... I told him he wants me to change my past and I can't... he said he doesn't need me to change anything he just needs me to leave him alone, told me I didn't do anything wrong and wished me "ALL THE BEST"... Some of my friends are saying it's a sign he's controlling, others think that to him meeting my parents was a big deal and I offended him and made him feel like I was less important... I really like this man and have shared more about myself with him than anyone before..I believe he mean it and wasn't trying to manipulate me, i think he was hurt by it... did I do something wrong? is he controlling? anyone had anything like this? SORRY ABOUT HOW IT'S WRITTEN. I'M NEW
