You will probably never have the same attachment to her as you would if she was your own.....but you either have to step up and play the role or go now. You and your fiance need to set the ground rules....together....esp if you are living together. I.e...bed time is this. What is and isn't acceptable behavior and what the punishment is for the unacceptable behavior. You can discipline a child without violence. Time out ... when used properly IS a good tool. Not in her room but in a place of the house she is not going to like. No toys, no fun, etc. A child needs consistency and discipline. Poor thing is confused as hell. Daddy here, daddy there. This daddy makes me walk the straight and narrow while mom and the other daddy don't.
You don't have to love her like blood.....but.....think of it this way. If you had a child with someone, you were divorced.......and another man was involved in raising YOUR baby girl on a day to day basis........how would YOU want her to be treated. How you treat her now....as she's growing up will greatly affect the men SHE turns into a young woman.
Good luck. Tough choices ahead. Make them with one thing in mind...that Child!
1. Once a cheat always a cheat!
2. YES, SHE can get pregnant the first time!
3. NO, PULLING out IS NOT a RELIABLE method of Birth Control. DAMMMMIT..... Wrap that shyte UP!!
Women over 30 are dignified. They seldom have a screaming match with you at the opera or in the middle of an expensive restaurant. Of course, if you deserve it, they won't hesitate to shoot you, if they think they can get away with it.
For all those men who say, "Why buy the cow when you can get the milk for free". Here's an update for you. Nowadays 80% of women are against marriage, why? Because women realize it's not worth buying an entire Pig, just to get a little sausage.
What the mind can conceive....the body will achieve!
