Just as a further update (maybe a long post). Another torrid evening. Wife tried to take youngest to bed, youngest refused, wife got angry and stormed out to go swimming leaving me to comfort little one and sort her out for bed.
When she got back I told her she can't just run away and has to make an effort. She just went on about me taking over and turning children against her.
Later I asked her if she wanted me to divorce her. She just shrugged. I told her she had to grow up and tell me what she wanted. She said she doesn't want to lose her home or children. I said that's not possible without me, and I said I wasn't prepared to live with her knowing she was carrying on with someone else. She got angry (again) and then said that legally I couldn't force her out of her home and we can live separately in the house. I'd suggested that weeks ago and she basically said f-off, so I said no, it's time to start moving.
Later, after more anger, she eventually shouted out, "i wish you'd both just f-off and leave me alone". I said who is "both"? She didn't answer, but it seems some posters on here were right in that there does seem to be issues with her and toyboy.
I also brought up the fact that she needs to tell the children and others, including her friends what's been going on. She then got her phone and showed me a group chat. It seems her and her friends have been having a good laugh about her affair behind my back using emoticons to describe things and just been nasty generally. For the first time in weeks I shed a few tears, as I saw she was having a laugh about what she is up to, despite the hurt I've been through and what's to come for our children. I just said to her that she is a horrible, nasty and selfish person and and unfit mum who should be grateful I'm not looking at pursuing full custody.
She misheard me and thought I'd said I was going for full custody. Pure volcanic rage from her... if you've watched the Big Bang Theory she looks a lot like and acts a lot like Bernadette. Really petit (over 1ft smaller than me) but with a huge temper and vicious tongue. Anyway, she demanded to know who was funding me, told me she'd take me to the cleaners, I would lose the home, she'd easily win, etc. etc. I just let her go on and on.
My final comment to her was that she should learn to listen. She looked puzzled, but id heard enough. I'm going to go to solicitors next week and start divorcing her. I'm sad my marriage is ending but I know that I've tried my hardest to salvage it, and I know I've done all I can for our children. I hope she can look back one day and appreciate what ive been through, put up with and the effort I've made, but I doubt it as she doesn't seem capable of anything other than selfish behaviour.
Looking back, I just can't believe my marriage has ended in this way. Its almost 13 years to the day we got married. I always thought we'd be together forever, and never once believed she'd have an affair. I never imagined I'd have to issue her with divorce papers... It happens to other people...
It's been a rough few months, but I think I'll be glad when it's over completely so I can move on. Tonight was the final nail in the coffin! And on that happy note, thank you for reading and goodnight!
