Wife and I separated 18 months ago, 2 boys 11 and 14. I moved back in with parents whilst looking for a house near my kids. I’m mid 40’s so no spring chicken. It was gutting, also very tearful all the time at the thought of why did things go south and not seeing my boys every day.
Imo getting upset is the right response it shows you care and that you understand the important parts of your relationship with your family. Getting drunk and shagging birds is a horrendously destructive approach. Backing off when things got heated shows both of you understand the importance of being reasonable.
My wife bought me out of the house and it really felt like I was being pushed out of the family, excluded and generally not wanted or needed. This couldn’t have been further from the truth, just my perception as I was the one leaving. It was the right thing though painful but right. Took over a year to find the right house. See my kids most days andmy relationship with the ex is really positive. Honestly the best thing we did, should have done it before in reality.
There is light at the end of the tunnel even though it may not feel like it right now. Pm me if needed.
