Is it cheating when ur on a break?

My bf and i have a 5mo old baby & for awhile shit hasn’t been good. We were renting a floor in his aunts house for a few months now until we got our own apartment but in our last argument he left and went to his moms & has been there for 2weeks now. I think a little space was needed because i realized a lot. So i told him i realized my wrongs & i hope he did his & i want him to come back home. He’d say “idk, i want to but all we do is fight blah blah” he’d give me a little hope he’d come back home just to tell me a few hours later he wasn’t which would make us argue again. I just think it messed up how he just up and left me at HIS family’s house.. anyways, i saw him yesterday & ask him to show me his Snapchat which he refused to do & walked away from me. He comes back and let’s me look at it obviously deleting a conversation & i started crying begging him to tell me the truth so i could feel free. So I’m not playing shit in my head trying to figure it out myself. He tells me he just swiped up on a girls picture and then she just sent him “🤪” and he wrote back she was cute & that she ignored him after that.. if it was just that why not show me? He made it look like there was more to hide. He said he did that because i was gonna “bitch” he then tells me when he went out to the bar his boy was chilling with a girl and her friend was talking to him and she was snap chatting and had him in a snap so he told her to add him which i don’t know why he brought that up cus supposedly that wasn’t the girl..? Anyways i get his phone and his most recent emoji was the 🍆 which means dick.. i started crying and asked him why he sent that and he said he was trying to fuck her... idk what to doo i need some advice. Would u consider this cheating while we were on a “break” you could call it?
