He asked if I would marry him😕

Last week my SO asked me if I would ever marry him. I stayed quiet and told him to hush and just eat his food. He said he was being serious and I kept insisting that he wasn't.

I'm not being rude. Here's why....

He wants me to be his forever but he doesn't trust me. His trust is almost non existent, to the point of getting mad at me for having any type of social media except Facebook.

This is a 7 year relationship with 1 child.

On and off, cheating involved and domestic violence. Why we've lasted so long only God knows. Anyways I used to want marriage but after everything we've been through I can't help but doubt that marriage is a good thing. My parents have been married for 24 years His parent have only been together with no marriage but with all the same issues we have. I wanted what my parents have but ended up getting what his parents have. He wants to marry me but as much as my heart would like that one day I think I'm too scared to ever do it. Not just with him but anyone! He also wants another child. I don't want anymore kids. All this because of my experiences in our relationship. I feel hopeless and just want to look out for the both of us. I don't ever want to hear someone tell me that they regret marrying me. 😞

Anyone ever been in this position?
