Having been down the divorce path once...and probably going again..I can tell you this...it's scary, emotionally speaking. For myself, I felt like a chump..not having seen the signs of adultery, the manipulations and emotional abuse.
I will say this...it's going to hurt..I felt like a failure, wondered what I could have done better...I didn't beg though...I wanted to keep that fragment of my dignity.
I won't suggest one choice or another, that's something you have to suss out. but yeah, either choice is a hard one..
I hope my rambling discourse helped
