Boyfriend problems☹️

So my boyfriend currently of 1.5 years has been sneaking around and entertaining females and recently got caught up. Yesterday Sunday afternoon after drill I went to my boyfriends house. We are chilling I eventually fall asleep. This dude is talking to some girl while I’m sleep, so I wake up and eat, and his phone is out of sight and I notice him leaning over the bed. So I get on him and look under the bed there his phone and Apple Watch. I’m crazy so Ik some dumb bs is up. I look thru his phone, sketchy stuff.. then I unlock his access and see this female message pop up. So I’m reading it. Pictures calls everything man I go tf off. I my feelings are beyond hurt. We physically start fighting then I left. Should I get back with him? Like I’m having bittersweet thoughts and I just feel so crazy idk y’all like I’ve been having the toughest day today.
