I am very, very pleased that you are in a position to ask him to leave and are not dependent on him for a roof over your head.
Just one thing, though.
Leave it until tomorrow, at least.
Far be it from me to think that Mumsnet has the power to make people end their relationships, but those kinds of accusations have been flying around for the last few days.
Speak to friends or family before you do anything irrevocable.
I know what I would do. But you are you.
You have been reassured that you don't have to tolerate this disrespect of you.
That realisation is power
Now break the secrecy, stop protecting him, and reach out in RL.
Take some time to get balanced reactions from people who know and love you (sifting out the people with an agenda who think this is harmless behaviour, because it isn't, often from women who overlook it in their own relationships)
but you are going to need support if you end it, and you need to get that in place, or you will cave again, when he steps up the emotional blackmail
because you know he will do that, and your defences will have to be strong
ok ?
