i have been dating my boyfriend for 9 months now. my ex. and i have been talkin on and off ever since we broke up but just as friends which we broke up 4 years ago we always run into each other. i promised myself i would be faithful to my boyfriend. but i went to my ex's house about month in half ago and cheated without protection. the day after i had confessed to my boyfriend and he told me that he cheated also.a long time ago with this one girl that i have been had suspicions about. well we both decided that we would try to make it work. but on the side i have and still am talkin and having with this other guy. a week after i had told my boyfriend and he told me what he has done some random number texts him and asks if he coming over tomorrow. but he does not text back. so i text the number without him knowing and the person texts back and said u came over last week and my name is "unknown" and u have a black car and blonde hair and described him to a T. so i called the person later that night cus my boyfriend told me that he did not know what this person was talkin about and when i called it was a dude talkin about yeah he came over and i sucked his and that all we did it was like at 12 at night. my boyfriend felt so ashamed he admitted everthing to me and he also told me that the day before he had with the first girl he ****** her friend. so he cheated on me 3 time 2 girls one guy. and he did not know 2 of the people. and know i have missed my period and am pregnant by this other guy and i do think my boyfirend is changing. but not so sure. he has quit smokin pot for me and everything. but tells me i have to get an abortion or we cant b together. the thing with that is i am confused on what to do which guy to b with. if i go with my ex i will be poor and he is possibly going to jail soon. and he has nothing nice he is a country boy. my boyfriend i will have it all and be set up for life cus military.but i really dont want to get an abortion cus i have had one wen i was 15 and regret every moment of it. please tell me what i should do i have never been stuck in this situation before i dont know who to choose if i choose my boyfriend i will not have a baby but i will be set for life. if i choose my ex i will have my baby but not set for life and b poor i am so confused please help me.i dont want to get an abortion cus i ****** up and opened my legs. and i know it up to me but i dont know which man to talk to or be with or end it with
