I'm so sorry for this situation. It is completely unfair to you.

It's no wonder you're so depressed. It doesn't seem that your wife wants to work with you to either terminate the marriage or save it.

Sounds like she's baiting you and gaslighting you.

The only thing that I could advise is getting a psychologist or counsellor for you alone so you have someone to talk to (in secret)

And, also document everything in secret as well as contacting a lawyer (also in secret) to see what your options are.

It's a heartbreaking situation, and you need to find solutions...

Many hugs
