I tend to agree with others on the child support issue. Child support does not have to mean you are out to get the guy....you can agree on a sum per month. Or ask the dad to put the money into a CD or something for the kids college fund. Thats distant, and very helpful.
Per a prior post, I was not aware that its best to have the child legitamized when born, for the child to be legally adopted by another man. The bottom line is how much do you trust this man (not much given posts in terms of how he may change in mind later), and are willing to take custody/paternity matters up with him 2, 4, 8 years from now? Does his wife know about this? If not he's probably safe, but what if he gets divorced? He may change his mind about wanting involvement with his child.
Bottom line, now or later, you cannot escape it if dad chooses to exercise his parental rights. Yes, it may take him time to build up with visitation, etc. should he choose to exercise those rights...but whether his name is on the birth certificate or not, he can always change his mind and your rights will not be any greater or less at that time.
I wonder if your refusal to allow him to help financially is to make sure he feels no ties/obligation down the road?
One thing is for sure, if you don't get dad to sign the AOP, and dad is still legally unknown, you are free to move where you want, chose your life. If dad chooses to request custody/visitation, depending on the circumstances at that time, you have less freedom to move where you want to raise child.
Sorry so wordy, in my minds eye thats about the only thing you really need to consider.
Depending on your answers re child support...if you are NOT concerned about dad responding to child support with custody/visitation orders, I WOULD totally accept monthly payments from him. Its not for you but for the child, and they are expensive. There is zero reason under the son why dad should not be helping you out. Zero. Your CHILD deserves it. You will be raising the child, its only fair dad pays for helping, especially as he does not want to be involved.
I understand the desire to have dads name on bc but that does not, well, this is my opinion and philosophy only OK?, a name on a piece of paper does not legitimize a child. I want to go look that word up in a dictionary. I am sensitive to it myself (I also am a single mom of a child born 'out of wedlock'). If legitimizing a child has to do with having two legal parents...then you would get that by dad signing the AOP. But to me, thats nothing. It has to do with a dad choosing to be a father. THATS the biggie you will have to deal with with child as years go by....the don't know anything about birth certificates. When/if the day comes that child needs to see dads' name....and its not there....explain that it was a mutual agreement that would help you to be an independent mom and to raise child as you saw fit.
