I’ve just found this thread again and have been in two minds about posting again. I do have some different views which I don’t think you appreciate. However maybe part of moving on is trying to listen to others views and not just seeking out people to tell you what you want to hear.
You must find things to fill up your mind. Going back to work is a must and I hope you do everything you can to get back on 1 June.
When having the counselling try and let the counsellor lead you and help you focus on dealing with your feelings and grief.
I’m really not sure that no contact and cutting yourself off is the best way for you. Perhaps be brave and talk to someone you trust who went on the Benidorm trip. Try and find out what he is thinking and doing (not with OW but about everything else(). Not cintacting someone is not a sign of strength but remaining dignified during the contact is.
He and others may think you are behaving oddly or It may be that he now thinks you really don’t care at all. I would have thought that telling him what a s**t he’s been but that you are bouncing back is better than hiding away.
You keep mentioning that all his friends are actually your friends who won’t see him any more. If they have been friends for over 20 years they are his friends too and they will probably see him even if they say they are not going to.
I have a friend who brought up her XH’s children and when they divorced (at his request) he told her that she effectively had to get lost as they were his children and she was meaningless to them all. I have always thought this was one of the most spiteful things I ever heard. The children see her in secret now they are adults. Your son may still want to have a relationship with the man who brought him up.
See a lawyer, you should automatically get half of the value of your joint assets. I know you have only a small amount of equity and savings but he may have a valuable pension pot. You need to know this because soon enough he won’t want to pay the mortgage and you need a plan.
There is no automatic right to spousal maintenance, you may get it for a short period. However looking after your Hs school age children for a few years will probably not be a strong case. Also you had a well paid job quite recently so it will be assumed you can find another.
My divorce cost £5k in total (me and XH) but we had agreed everything before we went to them and that was the cost of the legal and court paperwork. If you argue the cost each could be £10k and much more so no one wins as it will eat up the equity.
