So I was seeing this guy for a while, and long story short I got pregnant. I'm currently 10 weeks he left because he said hes not ready to be a parent. I just found out today by his friend that he has a 2 year old daughter with his last girlfriend. I'm not upset or anything and it's weird for me to think about my child having a half sibling but for some reason I want to message her and ask her if the baby is his because what if his friend was lying but I don't want to come off rude. How would I go about saying all this though?
