(Before I continue I posted this on the Ask FreeloveMD before I came to the forums)

I'm 20 and a guy.  I have a great friend, we were great friends when we were about 4-7, and we didn't see each other until I was 18 and she was 17. Thats when we started dating for about 3 months.  But to give you a great idea of who I am might help the answer to the question I'm about to ask.  I basically work full time and I am going to college.  I don't make no more than about 1000 a month.  I live with my parents...for now.  I am working on getting a good career that way I can support a family.

After we broke up, she got pregnant and gave birth to a handsome baby boy.  She is married but not to the baby's father.  They have been married I'd say not even a year.  Now just to let you know I really care for her and I'd do anything in my power to help her and her son, whether it would be finacially, physically, mentally, or emotionally.  I think about her ever once in a while after we broke up (just to let you know I'm not one of those stalker type people" lol). I don't know if I love her, I probably do but I'm not sure. I've only dated maybe 3 or 4 times total and none of them lasted no more than 2 months so there is no way for me to tell what love is.  Her husband is mistreating her and well there is more stuff to add but I'm just going to keep it there and I don't won't here to be with this prick, she isn't happy with him and I'm feel like hurting him if I hear that he hurts her again. 

I can't fully support a family right now but I know that if she is with me I will do my best to take care of her and her son.  But I would rather her be with someone she TRULY loves and he TRULY loves her and takes care of her and at least kiss the ground she walks on (just picking I like to have a little humor) than her be with me.

What do you think I should do?
