Hey hun, First fighting with his sisters will deff not make anything better between you n your x..Fighting isnt a good thing at all if your pregnant.. does he know that your carrying his baby? dont worry about his new girl friend.. are you keepng the baby even if you dont get back with him? I think the best thing you can do is consentrate on yourself and the baby... My best choice if I was in your situation would b 2 one act like you dont care that hes gone... a guy always wants what he cant have.. and two talk 2 him about your baby let him no that you are having one and that you would really like him 2 b there wit you threw this but if not ull b just fine wit out him... chil support is something you dont have 2 worry about until after the babies hear... but dont fight or you can deff hurt the baby!

definatly dont fight!!! and tell him your pregnant
