Wow, mine returned for 18 months because of his mistake.... I still think I let him move back in to quickly. My disclaimer to that was we did Gottman counseling and after 3 months "they" thought and he thought he was ready. It was right after his break up with his soul mate too. Looking back I should have insisted that he stayed out of the house longer.
I really wanted my family restored and really at the end of the day ...it would have ended either earlier or sooner. Mine is still in MLC.
My advice, sit back and see if he works on himself or starts spinning again if you don't jump at the chance. That will show what he really wants.
It's a hard place to be in emotionally for sure for you. Just don't be in a hurry to decide anything....
