she says we dont need to go to court
i can just come and visit her and the baby and support her
and depending on how that goes also fuck her 
Basically, she's telling you she'll be your whore by offering to let you fuck her. Only problem is, she's a whore with issues and that doesn't usually work out for the best.
As for the comment about your dad trying to get to her, I'd strongly consider the source. She could just be trying to make trouble. Some people thrive on drama. Also, she's probably smart enough to know that there is often some rivalry between fathers and sons. She may think that by telling you this, you'll want her back just to get even with your dad. Yep, some women are just that crazy evil.
