Sorry OP - I didn't read all of the thread - forgive me.
My ex called me a bully too - about the past rather than my behaviour after I found out about the affair. Said he was hurting, that's why he had the affair. It's very common for the guilty party to do that, as no doubt people have been saying.
My house was a state - partly because of the atrophy he had engineered - when he left I started to do it up - mend the rotting window frames myself etc etc. Gave me something to do inbetween bouts of weeping!
You can too!
The best thing I did was the day I decided never to speak to him again. That all conversation and contact was useless - went nowhere - round in painful circles. It's been about 2.5 years since I spoke to him, I don't even know his address. I don't speak to any of his family. I just went cold turkey. We have a grown daughter together, but we manage that quite well and are very respectful of each others parental relationship.
6 months after our last conversation he sent me a huge expensive bunch of flowers for my birthday, he did the same when I was very ill last year. I ignored both gestures. For me - if he wants a post relationship relationship he will have to do all the work and it will have to be one hell of a conversation completely driven by him. It won't happen.
Occasionally I feel like contacting him - usually in anger, but I never do and I am so glad I didn't after I have calmed down.
Day at a time. It WILL be ok. X
P.S - I've also had 2 relationships in that 2.5 years. Both lovely - not keepers, but lovely. Besides - I no longer believe in forever. I think the illusion of 'forever' causes a lot of pain and disappointment.
