Me and him we kiss we talk it's nice when we hang out alone but he said he doesn't want to be in serious relationship which I'm fine with it but he also has a girl best friend who always with him. He told me he doesn't like her but in public she would hold his hand and give him a kiss right in front of me and all my friends then he would be fine with it. oftenly he would bring her everywhere with him even on our date  sometime and  he would uses the reason"she's my bestfriend" I really like this guy and I want to solve this problem. What should I do? I tried to talk it out with him but he often just said the same thing.
