Flake.
Tell him to sod off, or if you're inclined - to go and get his head straight and to call you once his counselling is finished and his decree absolute has been issued.
I'm divorced - it's just paperwork. A lot of bloody paperwork I'll give you, but just paperwork.
If it's more emotional than that for him, then he's not ready to date, and it's not fair to you to fuck your around.
You're think poor wounded bird all damaged and I can stick by him, aren't you? I'm thinking - quite possibly manipulative arse. Only took you accepting his dumping of you for him to turn on the waterworks and try to drag you back in.
And here you are, 5 months in, feeling insecure because of a man dumping you and being so not ready to date that he's in counselling. Oh and he hasn't sorted his divorce out yet.
He's not exactly a catch, is he? 😂
Throw him back in the sea. Try again by all means when he's divorced and counselled, but keep your radar on for similar woe is me manipulative shite.
