I don't know who else to turn to...

Robyn • I am a single mom of 3 kids. Divorced.
My husband and I have had a lot of problems throughout our 7 year relationship (3 yrs of that married) I've struggled with depression off and on to add to it. We probably shouldn't have even started to try to have another baby and now I'm regretting it.tonight after a slight argument which is honestly nothing. He snapped at me about plans on Sunday cuz his psycho mom is having a bbq that I didn't know we were going to since he's supposed to work. I was going to go to church with my step dad and step sister who are in town for the weekend. ( they live 5 hrs away. His mom lives in town) he told me that he doesn't want to be married to me and accused me of not wanting to be married to him. Apparently he has had enough and can't take an argument where he isn't even letting me explain how I'm feeling or anything and makes me feel like if I don't apologize and forget about how I feel and if we have one more tiny argument we're through. I am 15 wks 5 days pregnant and I don't know why to do
