guidlines for parents?

So there was a question on the list that we looked at the other day about should there be guidelines for people or something like that before they are able to have children. We did not get to discuss it but i thought that it was a very interesting question. I look back to having kids and with my first one i was so not ready i was still in high school and i never even thought about it once. I never thought about consequences about having sex, (i guess i would not consider it a consequence because i love him to death!) but you know if everything was more laid out on the table. I guess i just did things to do them back then. But i was not ready then and if there was guidelines i would not have fit them! I wanted to party and be a teenager and that does not go along with motherhood i came to realize. But i guess i think about it from the aspects of looking at the mother is automaticly stuck in that position and the father can be easily off the hook. My oldest son's father has seen him once and that was when he was like 6 months old and has never done anything for him except pay child support which is mandatory and that is iffy some months if i even receive that. I really don't even think that i loved this guy ever honestly either he was just one boyfriend at this point in my life. But i feel really bitter towards him and i always have, it is not as bad now that i am older though, but i have always felt that he just walked away and never took any responsibility at all for a child that is also his and i guess i just don't understand how he could do that. And then i have the father of my second child that at one point in my life that i was in love with and engaged to, but he was verbally abusive to the point that i did not even have any friends anymore, because he did not like me having friends, hell he didn't even like me going to work or seeing my own family. He always totally put me down and i was not a good relationship at all and i took me two years to actually leave him, but when i did leave him i was to the point that i totally hated him. I stayed so long because i was pregnant and didn't want to go it alone with two children, but it was the best decision that i ever made, but i still have anger towards him because he has nothing to do with his child and he also has two other children from his previous marriage that i see more than he does. And i guess that it just hurts me to know that it is that easy for men to just walk away from something and someone that is a part of themselves also. Yes i do not like him but that does not mean that he can not know his child.
