Married but separate ?

Husband and I been together for 16 years. There’s been a lot of discrediting me as a mother and I can no longer take it this last time as pushed me to the complete edge. I told him I was to separate even though we are married. I only want to separate because I do believe we can work this out. But at this moment I need time for myself before this sadness becomes hatred and I don’t want to end up hating my husband because I feel like there’s no going back from that.

He just told me he doesn’t accept that shit “married but separated” but I really need time for myself. It really has taken a toll of me.

What are your girls thoughts and opinions?
