Hi fallenangel,
I know it's too late already, but do you have a cell phone? That is the number my T. will use whenever he has to contact me. He does have my home and work phone numbers but, because he knows I don't want anybody else answering my calls from him (family and friends don't know I am seeing a T.), he will only call me on my cellphone. This way I always get his calls or his messages. Maybe you can do that too, if possible. That way, you will always get to talk to your T. and not have to miss her calls. Just a suggestion. Take care.
