settlement agreement advice

Marisol • Stay at home mom :)
So my husband is pressuring me to sign the settlement agreement that states that I only get to see my 6year old daughter every other weekend while he gets primary physical custody. I can not afford a lawyer to explain to me what els I'm losing in this agreement and he's using that to his advantage that he's got 10k to drop on lawyers if he wanted to. My question is : 
If I don't sign this agreement by the 21 do I go to jail or do we get a court date and go to trial? Even if I can't afford a lawyer
