It's impossible to make an effective judgement on this.

If I was to translate as is, I would say this is a guy at his wits end.
Who 'feels' he has tried everything and doesn't know what else to do.
However, the fact he doesn't just leave, or ask for a divorce suggests he is just as invested in this to-ing and fro ing as the other party.
I would suggest,get a mediator or move on and stop making each other miserable.
