Married 10 years - two girls (8 and 5). Relationship always a bit dodgy - he was very controlling / I felt I was walking on eggshells a lot of the time / didn’t support me / criticised me, etc. He said he’d had enough and that he was leaving in the first lockdown, but didn’t actually leave til 7 weeks later. He’s now in a flat in the town and has the girls every other weekend and one night a week. I thought once he’d left (=got what he wanted), he’d treat me better, but it’s just as bad / worse. He msgs all the time criticising my parenting. The little occasionally bedwets - this is my fault. The older one struggles with numbers at school - my fault. He calls me awful names in these msgs. After he left, he went on Tinder and met someone - but he can’t now meet her because of Covid. I recently met someone (an old friend) and am enjoying this relationship - except that my ex is furious about it and constantly tries to sabotage it - recently through the girls. What can I do? I’m exhausted.
