Reply To: Stay or go?

I wondered the same thing as @Lucidity — some people stay friends with their exes and that’s ok! But I’ll give you the benefit of the doubt and assume he’s flirting and being inappropriate. If so, you have a pattern of bad behavior on his end and you don’t trust him (with reason). Leaving would be very valid, but if you did want to try to work through things, couple’s counseling seems like it’d be your best bet.
