Guys, I really don't know what to do in this situation...

I'm 23 years old living in Tampa, FL and I have a son who is 1 1/2 years old.

Currently, I'm giving my "wife" (we aren't divorced. Just separated and not even legally) $700 for my son every month. $480 goes to his day care and $220 goes to him for food and stuff.

Being honest, I was sent to a mental health facility for a weekend due to the fact that I almost killed myself. However, the doctors, therapists, whatever they're called, all agreed that I was just under severe stress. I had lost my job. She lost hers a couple months later, we lost our home, cars... Everything. We moved in with her parents and they didn't make the situation any better for us, causing more stress on me which ultimately led to my wanting to suicide.

Also, I've gone to another therapist after I found a new job and was myself again and even she agreed that I was just going through severe stress.

Anyways, I honestly feel as if she's just waiting for me to mess up or whatever so she can take him away from me completely.

Personally, I really don't know what to do or how much I should be paying monthly. I've tried looking into this and I get so many different results.

Please help me.
