I haven't had a Hoover for over 2 weeks now, He must have new supply.

Hi all.
i am in a werid place in the moment with my recovery, Am just on 3 months NC and i mean really strict no NC, No looking at his Facebook . My phone number changed, Except for My landline phone, But i do have call Barring. on there.
Anyway since we split and i ended it by the way after i found out he had stole money from my bank account, And lied saying he won a bet, When he never, It wasn't just that he was cheating on me with anything with a pulse too, So anyway he has been knocking at my house up until 2 weeks ago.
I know he must have new supply. But it hurts me, Because i want her to know what type of scumbag bastard she is getting herself involved with,and what he has done to me over the years.
I hate him i feel as though he will be treating her better and he is happy.
Its not fair why is he Happy and am not when he is the bastard who abused me for years?
I am so upset. Is this normal too feel like this? Or am I going mad?

Thanks xxx
