I have to tell you that I'm beginning to grow tired of arguments like the one you've put forward here.
Why?
Because if you really expect a man to behave as a responsible father you have to do a bit more yourself in order to achieve that.
For example, did you ask yourself whether the father might be a responsible person and likely to show committment toward you and your child before embarking on producing a child?
Did you ever love the man or believe he loved you, so that the child you both created might be born into that loving situation?
If you didn't do any of these things then you might as well have chosen to become inseminated using IVF techniques for all the right you've got to expect responsible fathering behaviour from this man.
In the UK the sperm donors right to anonymity was removed a couple of years ago, so that any child they fathered could seek them out if they chose to do so. What happened - men stopped donating their sperm apparently. All you can conclude from that surely is that some men are prepared to allow themselves to become a "father" but want no role thereafter, particularly in regard to children where they never had any real relationship with the mother in the first place.
I don't expect any kind of sensible response to my objections here, because I guess you will be immune from seeing where you may be going wrong.
I have sympathy with many people/mothers where things go wrong in their lives, and we've all probably had our rude awakenings when the people we thought we loved turn out to hate us with a passion or simply don't love us anymore anyway.
Some young mothers just want a child because they want something to love in their lives, and maybe they don't always think too much about wider consequences. If they do their best for the child, and the fathers can be found and persuaded to pay their dues for their actions then okay, this happens and maybe always will happen.
I never wanted a child by a woman I didn't think I loved, and really I can see no reason why women shouldn't approach this in the same way. If you can't love a man or find one to love you then maybe you shouldn't have a child, certainly not knowingly go down this path (unlike the young mothers who probably don't think about what they are doing), is that so unreasonable?
Alot gets said about the "rights of the child" on this forum and others like it.
You can't force a father to love their child no matter how you try, a man can't even force himself to feel that way if it isn't there within him for that particular child.
All you can do is to allow the possibility that the father might feel that way towards your child, and in most cases I believe that can only start where he loved you first.
Sermon over, as you will have guessed by now I doubt you can achieve your goal, whatever that is regarding your child and the father, but carry on if you must portraying this fathers as a "loser" or other stereotype you choose.
