Proper way to issue an ultimatum?

[amg2]

One of the EAs stopped ("ran it's course") before this D Day. The other was ended the next day. So he's not in any EAs and hasn't been since D day (I don't think). The problem is that it's been over 2 months since D day/he got kicked out of the house, and he still hasn't gone to IC. I told him I was willing to "discuss the possiblity of our M" if he was in IC. Not thinking about going, not talking about going, but actively going.

He has seen all along he plans to go but is "stuggling to get to the poing where he's going for himself". I'm just getting more resentful and tired each day. He has/is making gestures toward me, but NOT DOING THE ONE THING I TOLD HIM I REQUIRED.

(We don't have children.)

Thanks
