Boyfreind stayed out all night again til 10 a.m.

So i posted the other day about my boyfreind staying out til 6 am. Well he did it again lastnight he got off work at 10:30 pm lastnight and he never came home lastnight he stayed out all night and he didn't get in til almost 10:00 am. I was pissed. I pretty much know at this point that he's seeing somebody else and he kept telling me he wasnt going to let me leave him and i got him f**** up. Well i left , and he had the nerve to pretend he was mad at me for being mad at him for staying out all night... He didnt say 2 words to me wen i was gathering my things and left... He told me that im insecure and he swore up and down that he didn't cheat , he even let me smell his d*ck. It aint smell like nothing.. Ladies i know im not overreacting, am i ?
