My turn to ask for advice. (Long please read)

Ashley • Little Saskatchewanian lady in British Columbia
My b and I moved to another province a couple months ago and have been trying to integrate into a group of friends I met years ago. My Bf is having some trouble fitting in but other than that were ok. We've been fighting a bit because we're in such close quarters. Well tonight I let my suspicions run rampant and looked at his phone. Tinder. Was active a week ago. I looked at the messages and there's just one with him saying "tell me a story" wtf do I do? I already woke him up and asked how tinder was, and that if this is how he handles our fighting I don't find him mature enough to be in a relationship. But shpuld I give him another chance? Obviously a. Fucking dating app isn't for making friends so he can shove that excuse up his ass
