Thank you for the advice....

Miswimmy- I tried to explain to her how stressed out he was where she turned it into he's wired with a lot of head issues and that I'm a mentally messed up person.

Travelinglady-The thing is he did apologize to her 3 times and said he was grateful fir the night out. She took it as insincere and continued to attack him verbally in which case he left the car to walk home.

I have looked into the option of moving out but it won't happen for at least a couple of months until I can save some more money. It's just incredibly scary all these changes so fast. I guess I'm just very scared of ending up alone.
