This is a big reason I am against T's allowing email communication beyond appointment scheduling...It seems more people than not, get hurt and feel anguish related to some type of email issue. I'm sure he would change the rules a bit if he knew how distressing this is for you...or at the very least he would want to work through it with you.

I agree with HazelGirl. This could be very therapeutic if you are able to work through this with him and figure out where these jealous feelings really come from.
