Imdi, You have to do what feels right for you. If you're just feeling used it probably isn't a good idea. I've decided to continue ML with my H because I'm still enjoying it and I think he feels used.
These boards give great advice but at the end of the day it's your life, your decision and you have to live the the end results.
I wish you luck and send you lots of hugs ((((((((((Imdi))))))))). I know it's going to be a hard decision and one I hope I don't have to encounter.
