It seems you left a chucnk of information out.

I got that he moved home because there was really no w here else to go. But the way you described it was as htough he was back with you and not feeling separated.

It's time for some boundaries.
First...no more I Love You s

Now, if he is living at home, he WILL ACT LIKE AN APPROPRIATE SPOUSE.
Make that a boundary rule.
If HE CHOOSES to not be an appropriate spouse, then he also chooses to live somewhere else.--thus you are not the one kicking him out.

Appropriate spouse doesn't mean through the crisis, sleeping in the marital bed, affection.

Appripriate doesn't mean he will not yell and be angry, vent, push your buttons.

Appropriate means he abides by the mariatl vows--basically FIDELITY.

If he is MLC MArch was WAY too soon for a real return--March of next year would probably still be too soon. He will cycle and OW's cling. Read the resources and educate yourself on the process of MLC.

And...can you review why you think this is MLC...other than the infidelity?
