'Uh-huh, so it's your fault. Not his for not accepting a no. (You know that men are perfectly able to recognise a "soft no" as well as hard ones? Plus he's a therapist for fucks sake.)'
@category12 True. Thanks.
'You said I made a great analogy. So, do you see how his behaviour is wrong?'
Yes, I think there are lots of bits to it which will gradually slot together in my head. For a start I can see his encouraging me to 'spend too much on shoes' (have risky sex when I was hyper) was wrong. He knows what hypomania is and how it would effect someone, and he shouldn'tve done that. I think he got carried away with fulfilling his own desires/fantasies, and let them blind him to what was happening (and as you say @SirChing , that is the generous explanation.) I have no regrets about having done the cinema thing etc, but someone else easily could've done that stuff when they were hyper, and regretted it deeply later.
I was thinking for a moment that his sexual 'interrogations' are a form of sexual bullying, but maybe it's that he's trying to see what I might be up for doing/persuaded to do, rather than that he's deliberately trying to make me feel uncomfortable. I'll spell it out if/when he does it again, and make it clear how it makes me feel.
'What exactly is the friendship part of this relationship?'
We do chat somewhat, and spend a lot of time together. We play Pokemon together. 
He's not all bad I'm sure, but I'll be observing more closely now. He does let me talk sometimes, though he tends to often just tell me I'm thinking wrong, which isn't always helpful to me/people IMHO, at least early in a conversation, and in a way that grates. You can know inwardly that how you're thinking is wrong, and just be letting off steam. I had another friend who was like that, with her it came across as somewhat unsupportive/cruel. She would say people who'd hurt me were justified in things they'd said/done. Don't get me wrong, tell a friend if they're wrong in being hurt over something they're hurt about, but there are ways and means IMHO. But who am I to give an opinion on how to interact socially? 
I don't mean Mumsnet- you lot can be as brutally insightful as you wish, and I expect and desire nothing less.
'He fucked off when you were struggling.'
Yes, that wasn't good. He'd say he had to do it for his own self care. At the time it made him seem like a fair weather friend, and also made me feel awful about myself.
I think he's pretty much made up for it since in the amount of time he's given me. Though I was disappointed a few days ago- I would've wanted to talk about some things and had even thought up bits of conversations in my head, only for him to go on about sex as soon as we met up. But he was having a bad day that day.
^'you are spending so much mental time and energy on a man who you aren’t in a relationship instead of focusing on healing yourself.
He’s an addiction, like smoking or booze, you know it’s bad for you but you convince yourself you need them. You don’t.'^
@Zofloramummy Yes, that's what one of the therapists said. She said people/I use things like food, booze, him or sex in general as a 'bounce,' to give them a temporary boost in self-esteem. It prevents them/me from doing the work, as you say.
