Relationship advice

Okay so I've been with this guy 6 months and he has treated me like gold I mean did everything for me stuck around when I was difficult and all but 2 weeks ago he broke up with me because I asked him to delete a girl off of snap chat because I honestly felt like she was threatening our relationship and he refused to do so, so he ended it. Then a week later he had concert tickets that he bought for me and he ended up taking another girl who has a boyfriend to an over night trip to this concert.. Now he's begging for me back? I feel like he was being sketchy. Now I'm confused, should I give him another chance or move on? I'm just tired of things like this happening. Need advice!
