At the end of the day it is your decision whether or not you want to keep it. If he is not ready to be a dad then you can't really force him to stick around either so you're going to have to accept that it is a very real possibility that he will leave you and you will have to raise it yourself which isn't easy. Also bear in mind that if that does happen it will have an effect on that child and that effect can be very drastic. Take me for instance. My dad was a dick my mom raised me herself and given my experiences it has absolutely ruined my perception of love and relationships. I'm currently avoiding sex and dating until I save up enough money to get a vasectomy because I am committed to making sure I don't pass on the failures of my parents onto another kid. Altogether I'm not even sure I'll date once I do because I can honestly say that I have given up on this thing people call "love". It could very well turn up shitty either way. The question is whether or not you are willing to take responsibility for your actions and bear the weight of your choices yourself or whether you will potentially risk dragging an innocent child into all of this as well. Keep in mind I say RISK. Everything might turn out ok but if you decide to keep it you are rolling the dice whether you want to or not.
