Hi MG - I'm so sorry you're going through this. The only thing I can say is to go with your gut instinct. It's usually right on. If you need to follow your heart then do so. Just don't beat yourself up over it if it turns out to be that he's just trying to get you to feel sorry for him and make it all better. If that's the case then you'll know better next time.
My prayers are with you!!
Love,
Galnva
