@Interlaken I take it you have never been abandoned with no explanation and 3 young children? I have, your comment is utterly ignorant and offensive, so off you hop and have a Calm day. 👋
OP, I have been in your situation but many years ago. In my situation it resulted in finding out there was another women, and then some. We'd been childhood sweethearts, life was looking rosy and we were financially well off for our ages at the time. My ExH always thought himself to be 'cool' but was clever enough to disguise that to the general public. He was also rather lacking in emotional intelligence. The 'breakdown' I initially thought (he was having (he was a workaholic through choice) included cocaine, cannabis, and as I said before, other women oh, and a trip to Amsterdam - evidenced by what I found on my computer 🤔
I thought we were a happy family. I felt so foolish when I found out as liking back there were tiny little signs.
The shock is horrendous.
My GP, family and friends were a fantastic support at the time. Medication like Diazepam and SSRI's also helped enormously.
I had to go through a very long court battle in the end that concluded at Crown Court, (how embarrassing) and also included an injunction when he wouldn't stop letting himself into our (now my) house in the early hours, taking papers and documents and being abusive towards me.
He also suggested going to Relate, when I started to query certain things, which would always result in an argument, him twisting my words making me feel I was going insane.
He was the only one who knew exactly why we were there-I was oblivious at the time, he was having the affair and lied all the way through the therapy.
I sincerely hope this has a positive outcome for you, but I would be getting my ducks in a row and make sure you have knowledge of all financials; pensions, insurances, bank accounts, kids bank accounts-absolutely everything. Also see a solicitor and make sure he can not remortgage the house. It can be done quickly and easily.
We are stronger than we think we are.
Sending hugs 🤗
