Thanks everyone for your input. It is good to hear what other's views are.
Before we separated we had ( or so I thought) the ideal life, I have a good career , we have 2 lovely kids, we had a beautiful big house. I still work out and keep fit and active. What more do you want?!
He had lost his job and while I was out at work he was having a relationship with a student he met who was less than half his age, such a cliche. At the time I was unaware , he said he was depressed and wanted a break and decided he wanted to be on his own so the house was sold we went our separate ways. Obviously the real reason being because he was lying to this woman and it was too difficult to maintain sharing a house with me.
I was heartbroken, but bought a little cottage as a renovation project for me and the kids and just got on with things. But we kept in regular contact. ( I still didn't know about her)
Anyway after a while he said he wanted to move back with me and the kids, he used his share of the house sale to open his business. He seemed sorry he had left and was keen to get back together and be with his family.
Things were good for the first 10 months or so until the OW got in touch with me, they had falllen out in an unpleasant way and had been sending horrible texts and emails to each other. She wanted me to intervene and resolve it claiming, she thought I knew about her all along.
Up until that point we seemed happy again. Since that came out and all the details of the sordid past I just struggle to believe him when he says anything now. Even though he insists he is not doing anything. I feel humiliated I didn't see it and had I known I would never have let him come back. But the trouble was I only became aware after it was long over .
I am paranoid now that he is still pulling the wool over my eyes. We barely communicate now, I try and talk to him but he can't deal with my 'heavy conversations'
He has been planning this trip while I am at work, I don't even know the details of it he has just said he is going away for a month.
It is the lack of consideration for me in even asking my views or listening to my concerns that are really upsetting.... who does that?
The good thing is I don't actually need him for anything, I have my own house, car, job and friends . The sad thing is I only want to be a happy family.
