baby drama

ladies what would you do if your boyfriend/boo/significant other already has one kid and you found out that there is a possibility that he may be the father to another?!?!

scenario: you two broke up for about five months, got back together and now you have been together for a year and a month strong (problems of course but no breakups or big blow outs). you just recently found out (like a week ago) that there is a female out there claiming her five month old daughter to be his and he has known about it for a month and havent said anything to you about it, you find out from his sister over twitter and when you ask him about it he gets mad and flips it (well try to) on you saying you are being nosey and worrying yourself about things that dont concern you... oooo yeah and you two have been together for four years on and off
