So lost...

Been married a little over a year and I am currently 17 weeks pregnant. I gave up everything for this man and in return I got an std (yes I’m sure he gave it and I didn’t find out till after I was pregnant), lies, excuses, and heartache. From cheating and justifying his actions to emotional abuse and threats, I just can’t handle it anymore. How to I go about filing if I’m pregnant?! I have nothing to my name and I’m beyond terrified... there’s no way I want this horrible person in my life let alone my child’s!!! What do I do? I need to get away...
