My ex-T abandoned me. Yet one month later, I started therapy with current T. I didn't trust her. I didn't really even trust myself since my judgement of ex-T was so off. But the reason I sought therapy right after the abandonment is because I couldn't cope on my own. I truly believe I would have died if it wasn't for current T. But mind you that it wasn't easy. I thought about leaving T many times. I even went T shopping. I don't know if it was my instinct or me not wanting to find another T, but for some reason I stayed. I'm glad I did.

So I don't think you can just expect yourself to trust someone, especially someone you can't be in the presence of. You have to want to try to develop a relationship with someone. Then trust can be built.
