May be the birth has scared him a little... You know the reality of being a daddy...
Judging by your post you are both young, and for dads especially the whole idea of bringing up baby is sadly still a scary one.
Lads wanna live their lives... baby stops you doing this... You do really need to talk to him about what he feels is happening and calmly talk to him...
Dont let your flirting go any further until you know what is going on with your B/F
Dont stay together for the sake of the baby as you will end up resenting each other... you may get on better as freinds.. I speak from experience

It is not an easy one it take you talking to him to let him know how you feel and vice versa
