That's a fallacy, Adam; it's no more uncontrollable than any other biological urge; I don't see you having sex with every woman you meet because, we all know, men have to have sex all the time?

It does not sound like you can support a child at this time, fernendo, give a child the fathering you believe a child should have? That's all you can go with, pretty much as that is your part, being a good father. If you have doubts about that role for yourself, whether you will be around or the mother of your child would be a fit mother, etc. then you probably should not have a child right now?

It does not sound like your girlfriend is able to care for herself adequately and I would not want to be a partner to bringing another person into the world in that situation; my husband had children from a previous marriage and made it my decision whether to have children with him when we married and I opted not to; I would want a father for any children of mine who wanted those children too, it's a joint decision and he was opting out. I think if you are freaking out, you should opt out at this time.

There's nothing wrong with not having a child and "wanting a baby" is, as Adam points out a biological urge, I did not hear anything in your description of your girlfriend that she is interested in raising a child with you.
