Personally I think you still give him way way to much of yourself...the tm's that he sends I wouldn't bother with...if you have someone at work let them answer the phone...or if you do and it is him just politely say, "Please don't call me at work...or really there is no need to call me unless there is a problem with the kids."
You need to cut the rope that binds you two...he needs to sink or swim...this floundering is doing none of you any good....
