So he is an unremorseful serial cheater, who, this time, is suddenly remorseful?
I think you're right to be skeptical.
Other than saying he is sorry and helping around the house, what is he doing? He needs to be in IC to fix whatever is broken inside him that allows him to cheat in his relationships. If he isn;t willing to go to IC, it would be best for you to have him leave now. Otherwise, he is just pretending to be "good" now, but after awhile, he will go right back to his shitty treatment of you.
Do you have full access to all of his accounts? Phone, Facebook, bank,etc? Passwords included?
Has he sent a NC email to OW? One that you approved of and sent?
Has he been tested for STD's? Have you?
Is he answering all of your questions without anger or defensiveness?
Is he aware it take 2-5 years to heal from this shit? And..that's if he is remorseful, not TTing you, and working on himself in IC.
What is he *doing*?BS(me)42
