This is very unfortunate. For starters, you cannot make anyone be more understanding. If you continue to pursue her and try to see your son, it can be very bad on your behalf. If she okay with lying she ok with filing a false restraining order against you. Sorry dude but you can fix or change crazy. Sounds like the relationship ended on bad terms.

Do you have evidence of your busted lip? Do she have evidence of anything that could be used against you(Literally anything, has she called the cops on your before abuse related or not)? Had she had any bruises she could taking photos of.

I'm not going to lie, I saw your edit the post but, your best bet here maybe to just wait until the child is old enough to reach out. In cases like these, it's a women's world and the odds are HIGHLY against you.

How can you prove that you did not abuse her? You know what I'm saying.

Also if your telling her you want to see her son but not her, she ain't Gunna let you see him lol. bitches are petty.

I would suggest, just also highly suggest not to, message her here and there and let her know that you are there for HER and the baby.

Is she still with the guy she cheated on you with ? That could also be a factor. She could be claiming the child is not yours. Are you sure the child is even yours. You seem so sure but no test.
