Dude on the Side

So I have a boyfriend of 6 yrs and a friend that is a guy of about a yr... I just found out I was pregnant by boyfriend and my first initial reaction was to cut all my other guyfriends off but now I'm having second thoughts... What would you do if you had a guy friend who genuinely cared about you and wasn't mad that you got pregnant just thought it was crazy because he thought he had the chance of being more than a friend... Seriously what should I do?
