c'mon guys the kid just had a fuckin kid. it doesnt matter who you are this is an event that deserves encouragement and congratulations.
best of luck glad and please be as great of a father as you have been saying you want to be (i dont doubt that you will be). and just because you have a kid with this woman doesnt mean you have to be with her or give it another shot. dont rush into anything dumb with her. work on yourself, being happy, and being strong and successful as a man - for the little one!
