Sarah if anything, it sounds like he is embarrassed by your pregnancy, and more than likely, its because he doesn't want to discuss over and over again that the baby is not his, and yet you are a couple anyway. I can't find any other reason why he would try to hide you in public situations. You need to just ask him, and if that is indeed the case, you really need to decide if you are willing to let him continue to treat you, and later on, your daughter, with that lack of respect. He knew you were pregnant when you got involved, and he chose to have a life with you anyway. He either needs to step up and be a man, and be okay with the decision he has made, or you need to focus on what is going to be best for you, and it seems that being without him might be your only option.
