I can imagine how painful this must be for you if your feelings have lasted for several years. I'm really so sorry. Would it be possible for you to propose some sort of transition plan with him? So you could have a couple of months to taper off and find someone else? Maybe one email a month for 3 or 4 months, or something like that. Ask him for referrals or some suggestions for how to make this easier for you?

It just sounds like a really painful situation. I think it would help if you had another T to help you work through this. Don't worry about becoming attached again or feeling like you have to trust, etc. Just someone to talk to while you sort through the pain, so you're not alone.

I'm so sorry - this must be so difficult.
