I'm in a loveless, abusive at times marriage to my wife of the last 6 + years.

There's too much to explain but I'll add some highlights:

1) Less than 6 months in to our marriage, she cheated on me with someone and still won't tell me who to this day.

2)She's hit me too many times to remember. Including slapping me real hard for what she thought nudes of some other chick. In reality I was in a messenger group chat where someone shared celebrity nudes who got revealed.

3) in the past year I've started to take my health more seriously, I've lost weight, set fitness goals because I'm trying to improve my health and she has stated multiple times that she doesn't want to do that.

4) she's been verbally abusive to me too, multiple times a week even jokingly she calls me a fat fuck, or fat ass or dumb ass or dumb fuck.

Im planning an exit strategy to get out of this in the next 2-3 months.

We have no kids, she hasn't worked for seven months by choice. Can she try to from me spousal support because she hasn't worked for so long?

What are some things I definitely need to get in place?

Any and all help is greatly appreciated.
