You are doing remarkably well OP considering the shock you have been through. I was in your position almost 6 years ago to the day - I got the "I love you but not in love with you" speech. DH moved out within the week (to OW that I knew nothing about). Those weeks were the most traumatic of my life and unfortunately, as they were older, for my DCs too.
I got through with the help of friends, family and Mumsnet (the poster "Whenwillifeelnormal" was a lifesaver at the time). I even phoned the Samaritans at 2.00am one desperate night
. My DH and I have repaired our marriage but he was living with the OW for 6 weeks and even took the DCs to hers without me knowing [anger].
Can I just say, please don't make any life changing decisions atm, it is recommended that 3 months is a good time when the initial shock has warned off. Please protect yourself legally and financially (especially with regards to the house, your interest needs to be registered ASAP). When I was a child in the 70's, my parents bought a house and on moving day they turned up to find the wife and children in residence with no idea their husband and father had sold the house from under them
- my parents' solicitor gave her a week to find alternative accommodation and we had to stay with relatives.
Please do not underestimate what your H will be capable of, he is no longer your friend - friends would not treat each other like he is treating you.
Please be very kind to yourself and allow others to take care of you, you have mentally been hit by a bus and need intensive care. I ended up on diazepam, weighing under 7 st and surviving on microwave popcorn.
Take care, one day at a time and this too will pass were my mantras
