LIT, welcome to JWN.
Seriously, RUN! I can honestly say us JW & xJW have loads of issues, but at least we are one, or the other.
The absolute worst person to be involved with is someone who is leading a double life/lying to themselves/lying to you.
OK, now I've seen that you were involved before and I'm imagining the romance of it all. ....still, he needs to sort himself out & come to you as a divorced xJW, or stop messing around.
I hope it works out for you!!!!
