DH and I have been married for 15 years, 2 DC age 10 and 13. He moved out in November 2020 and is asking to come back at the end of summer.
Background: I think we're not compatible in that he probably is autistic and quiet, but in the early days was good at masking and love-bombing me. Whirlwind romance. Tbh I was also susceptible as I was 39 and didn't want to miss the boat with regard to kids. I was lucky to have 2 DC in quick succession. After 3 years the relationship went downhill and we didn't have sex again after my youngest was born. He moved out of the bedroom due to my snoring, his restless legs, and his medical condition, which means he has to get up in the night to use the loo. He also had ED, which I overlooked, wrongly thinking that sex goes down anyway in a marriage, and he didn't want to seek medical attention for it. Tbh, he didn't think about my needs that much. Refused to pleasure me or touch my vulva, refused to seek medical help for ED, refused marriage counselling etc. then would behave like anything sexual was "rude" and he couldn't have "sex with the mother of his children" all a bit strange. So we've been living like flatmates for many years. He, meanwhile binge eats and is nice to the kids when they are nice, but can't help them with the difficult emotions, just shouts at them or ignores them. As I said, I think he is autistic.
Roll onto COVID lockdown and one of my DC who has special needs, high anxiety and lots of arguments between DC and DH, fights, police coming round 4 times in the past year, social services etc. All of the focus on DC, when actually, looking back DH was a big part of the problem. He couldn't meet my needs and couldn't meet DCs emotional needs either.
We decided to separate by mutual agreement last year (although I would say he checked out of the marriage years ago) and to be honest it felt like a relief because he would threaten to leave me when had arguments over the years.
Now he has been away for 3 months, he has visited at the weekends , helped with housework (he has always been good at housework, gardening, ironing etc.) and done some of the school runs, he wants to come back. I have kept my dignity by not blaming him or making him feel bad, the house is tidy, the kids are relaxed (well one of them is miserable that DH has left) but overall we are coping after the initial shock of him leaving.
He says he will change and is now talking about marriage counselling. Personally I think my DCs needs come first and they would be better off without him, but I feel sad that my family unit is broken and I feel sorry for him, should I bother?
