Trixi trying to find moorage

[Dom R]

I just need to get to the point that I don't care how he responds to that.

actually, maybe just the opposite. Maybe what would be even better, would be when you get to the point where if he responds negatively, you get pissed, and say, "FINE, the hell with you then!"

you may interpret that as "dont care". I would interpret it differently.

Or perhaps by "dont care", what you meant was "ready to kick him to the curb" or "not afraid of him rejecting you".



PS:

Because obviously, he will NOT respond in the way I hope

I dont think you can know that for sure. It's a matter of whether he really believes you are serious, and mean what you say, about "shape up or ship out".
If he BELIEVES you, I think he might respond positively.
Trouble is, right now, you've given him no basis to believe you.
