I'll try and make the long story brief, but include all elements.
3 years ago then DH told me he had been having affair for 6 months initially I tried to make it work, when I found out he was still seeing her we split. He set up bizarre relationship with OW.
18 months ago he us arrested for Drink driving with OW (alcoholic), DD and OW'sDD in car convicted lost licence for 12 months 3 weeks and 2 days?!? I restricted contact to EOW due to his inability to take to and from school, lived 7 miles from school no public transport.
Then he and OW verbally abused DD all came to light through DD revealing to teacher at school and then CP officer, probably the very worst day of my life. Stopped contact completely then over 12 month period through massive effort on my part rebuilt DD's relationship with him and contact restarted. I would drive for 1.5 hours so they could have contact for a couple hours in a public place and then drive back.
There was property beyond the house in our settlement and he got a flat above one of my business premises. Which yesterday he moved into whilst I was working there. Nature of work is that I am in and out of waiting room which is in 'shop' window. Through out the hour I was there OW paraded up and down passed the window on multiple occasions.
WTF first I have never ever engaged with her and never once ranted or raved, I just ignore so it was never going to provoke that reaction. Secondly if you are doing the alley cat thing pissing around your territory your welcome to him as I know he is working on cheating on you as another single has seen him on a dating website.
