PREGNANT & BOYFRIEND TROUBLES HELP ! (LONG SORRY)?

OKAY MY BOYFRIEND AND I HAVE BEEN TOGETHER FOR A YEAR AND 6 MONTHS . IN THE PAST HES FLIRTED WITH FEMALES , ATTEMPTED TO CHEAT (BUT DIDNT GET TO DO IT) , TOLD ME THAT HE WAS GONNA STOP TEXTING THIS CERTAIN FEMALE AND HE DID BUT A FEW DAYS LATER SHE TEXTED HIM AND HE TEXTED HER BACK , GOING AGAINST MY WORD AND HIS . ANYWAYS I CHOSE TO FORGIVE HIM AND KEEP GOING FORWARD WITH OUR RELATIONSHIP AND HES CHANGED ALOT SINCE HIS PAST EVENTS . SO HES IN TRANSITIONAL HOUSING AND HES BEEN IN THERE FOR ABOUT 7 MONTHS , AND THIS GIRL JUST MOVED IN ABOUT 3-4 MONTHS AGO . HE TOLD ME THEY TALKED A FEW TIMES BUT THEY WOULDNT BE FRIENDS JUST ASSOCIATES , I TOLD HIM THAT I DONT LIKE HIM GETTING CLOSE TO FEMALES OR FEMALES GETTING CLOSE TO HIM BECAUSE FEELINGS MIGHT START TO HAPPEN . SO HE DECIDED TO CONTINUE TALKING AND GETTING TO KNOW THE GIRL ANYWAY AND OVERTIME THEY BECAME FRIENDS . SPENDING TIME W/ EACH OTHER IN THE BUILDING EXCHANGING PHONE NUMBERS . HE TOLD HER HE HAS A GIRLFRIEND AND A BABY ON THE WAY AND SHE TOLD HIM HE RESPECTS THAT . NOW, DURING THE TIME HE WAS GETTING TO KNOW HER I WOULD TRIP OFF HIM ABOUT IT BECAUSE I DIDNT WANT HIM GETTING CLOSE BECAUSE OF THE WHOLE GAINING FEELINGS THING . HE DIDNT LISTEN TO ME HE THOUGHT I WAS JUST TRIPPING OFF OF HIM SO BASICALLY WHEN HE THOUGHT I WAS TRIPPING AND NAGGING HE WOULD GO TO HER . NOW HE TOLD ME THAT SHE TOLD HIM SHES STARTING TO HAVE FEELINGS FOR HIM AND I DIDNT THINK NOTHING OF IT REALLY BECAUSE HE DIDNT HAVE FEELINGS FOR HER IN THAT WAY AND HE KNOWS HIS BOUNDARIES . NOW THE OTHER NIGHT SHE HAD A BREAKDOWN OR WHATEVER AND THEY WENT TO A SECLUDED AREA HE PRAYED FOR HER AND HELD HER OR WHATEVER AND SHE TOLD HIM THAT SHE NEVER HAD LOVE FROM HER FAMILY AND THAT SHE FELT LIKE SHE WAS AT THE POINT WHERE SHE LOVED HIM . HE TOLD HER THAT HE LOVED HER TOO BUT NOT IN THAT WAY AND SHE TRIED TO KISS HIM BUT HE BACKED OUT OF THE WAY . HE TOLD ME THIS YESTERDAY SO THAT SAME DAY I TOLD HIM I WANTED TO TALK TO HER FACE TO FACE BECAUSE WHAT SHE DID WAS DISRESPECTFUL KNOWING THAT HE HAS A GIRLFRIEND AND A BABY ON THE WAY . SO HE AGREED AND I ASKED HIM A CERTAIN QUESTION AND HE WAS MAD AND HESITANT ABOUT ME ASKING THE QUESTION . I TOLD HIM I DONT CARE IM GOING TO ASK HER ANYWAY , THEN I ASKED HIM IF HE HAD FEELINGS FOR HER AND HE DIDNT SAY ANYTHING SO I TOOK THAT AS A YES . WE HAD THE TALK I CONFRONTED HER ABOUT IT AND SHE SAID SHE WASNT GOING TO APOLOGIZE BECAUSE SHES SINGLE AND SHES NOT TIED DOWN AND SHE CAN DO ANYTHING SHE WANTS TO DO BUT SHE ADMITTED THAT IT WAS DISRESPECTFUL AND THAT SHE WASNT IN HER RIGHT MIND AND SHE WAS VULNERABLE . AND MY BOYFRIEND ADMITTED THAT HE HAD FEELINGS FOR HER AND HE SAID I CAUSED IT BECAUSE WHEN I WAS TRIPPING ON HIM ABOUT GETTING CLOSE TO HER I WAS PUSHING HIM AWAY WHEN ALL I WAS DOING WAS TRYING TO PREVENT THIS RIGHT HERE FROM HAPPENING HIM HAVING FEELINGS FOR HER . SO NOW IM SO CONFUSED ANGRY AND HURT AND IT DOESNT MAKE IT ANY BETTER BECAUSE IM PREGNANT . AND I REALLY JUST WANT TO LEAVE HIM BECAUSE I TOLD HIM FROM THE START ABOUT THE WHOLE FEELINGS THING AND EVEN HE SAID I WAS RIGHT ABOUT THIS AND IM VERY ANGRY ABOUT IT , PLUS THEY LIVE IN THE SAME BUILDING SO ITS LIKE THINGS ARE NEVER GOING TO BE THE SAME BETWEEN US WELL AT LEAST NOT WITH ME BECAUSE THIS IS MESSED UP AND I TOLD HIM . SO I REALLY NEED SOME ADVICE ON WHAT TO DO . I MEAN HE WAS HONEST ABOUT EVERYTHING BUT THIS COULD HAVE BEEN TOTALLY AVOIDED AND PREVENTED BUT HE DIDNT TAKE THOSE STEPS BY NOT GETTING CLOSE IN THE FIRST PLACE . AND I FEEL JUST COMPLETELY IGNORED AND LIKE WTF ? YOU KNOW ? THROUGHOUT THIS RELATIONSHIP IVE BEEN FAITHFUL AND EVEN WHEN HIM AND I WOULD GO THROUGH OUR PROBLEMS I WOULD NEVER SEEK ATTENTION OR CONVERSATION FROM ANOTHER GUY BECAUSE I KNOW THAT WOULD CAUSE COMPLICATIONS AND I JUST FEEL LIKE WHY CANT HE DO THAT FOR ME . PLEASE HELP ME SOMEONE .
