[Yogi and mamma]

so i will try to catch you up and make it short as possible. so every month i always get this feeling of unhappiness and the need/want to leave my boyfriend. at the end of july i broke up with him and moved back into my moms house about 2 months later i caught a girl in our old apartment hiding in the closet i was so mad and he yelled for her to get out, after that he begged me back i got back with him. when i asked him about the whole girl thing he lied about everything i heard she stayed there 2 times and i know we broke up but if he still loved me why would he get with another girl? he must of planned having sex with her if he even got a condom from his brother?! he said he had sex with here because he missed me and he felt alone?!? but anyways he later on after a month getting back together proposed to me i said yes. and now i found out that he still hasnt told his parents after 3 months that we were engaged he says because there not close like that but i think thats still wired, so i gave him the ring back i thought that if he really wanted to get married to me he would give it back soon. but he said he wont give it back till like jan, or feb. to me thats strange too. i keep feeling like maybe i am holding onto are past because we had a kid and lost it so i keep thinking am i holding on to that for an excuse to stay with him? and if so is that right of me? i dont want to make a mistake. i dont know what to do? please help me. stay or go? i love him so much and it will be 3 years soon.
