I understand where u comin from and you make some good points. If you know you gon eventually want kids but with a chik who don't want anymore then you just gotta decide what's more important to you at the time.
As far a dealing with a bytch's bad ass disrespectful kid. Look..startin out you just there to fukk. Not discipline, be a role model, all that shyt. Now as time progresses and y'all get serious, if the kids hav a relationship with their father (visitation, child support) that's still his job not yours. Now if the little fukkers are living at YOUR CRIB it's a different story. And you can establish that with their father that at your spot you gon pass out a few "sit the fukk down"s and if he don't like it he can gladly come get the lil b*stards.
If the kid hits you wit "you ain my daddy" ..hit him wit "duhhh" and keep it movin. A real man don't let a child hurt his feelings so I don't get why these idiots keep throwin that out like its gon make you
nikka please, your moist ass isn't going to say "duh" when you've raised some other nikkas child for the last 5 years and he's hit you with that shyt that make your soul burn slow.
That is such bullshyt You've invested time in the mother and child, and ultimately he/she is going to hit you with that "You ain't my daddy" shyt and you're going to take it to heart.
