You never know he may have grown up to where he wants to step up and be a dad if the situation occurs. It is important however to know why it didn't work out with his exes. Was it all about his lack of commitment, or did he just not have a great relationship with them? It's important to find that out.

The real question is do you want to have a child with this man? It sounds to me the relationship is shaky to begin with. There is a lot of uncertainty in your words and it seems to me that you really don't know this man all too well. Tread carefully and make your own choices. If you don't want to have a child, get birth control or use contraception. Good luck.

Are you trying to get pregnant? I think you should consider discussing the possibility with him. His reaction should give you a good indication of what might happen if you become pregnant. Is he supportive of his other children? How does he talk about their mothers? I would not be comfortable in that situation.

I do not think that anyone can really answer that question for you. But I will encourage you to look at what you want out of the relationship and how the relationship is going. If you are with a man and fear that he will leave you if you get pregnant, then you may want to re-evaluate your relationship. Or if you feel that you cannot have an open conversation with him the possibly of getting pregnant you may need to reevaluate the relationship. If this is your fear. You need to first practice safe sex first so that you do not get pregnant. Also, know that you deserve the best in your relationships, and wondering if a man is going to leave you if he gets your pregnant, does not sound like a solid relationships. If you have to wonder that question, then you should make sure you take pre-cautions so that you do not get pregnant. And evaluate if you want to be in a relationship with him.
