Hmm I wouldn't call him unless it was a true crisis. I have called T once on weekend and he immediately answered and sorted it out. I AM respectful of his personal time. I DO email him throughout weekend sometimes daily like were agreed on and sometimes I spam. I do NOT expect a response. He has a life and I know that.
I would make sure you clarify this with him next session. Contradictions can be super confusing and hurtful. If it is an emergency I would call but if your just looking for a connection (which is perfectly understandable) I would email and wait for a response. The only thing that sticks out to me is that your on his fb? I would think that would be really hard to maintain boundries? I know me personally I would probably posts things just for a reaction. Like especially if I couldn't get a response, through email. (just being honest)
I hope you feel better.
