I have had an extremely topsy turvy relationship with the ex. We have a 6 year old child together. Spent 3 years on and off living in separate bedrooms (which aside from other issues I prefer because she and I wake and sleep at slightly different times).
Initially in the relationship I put her on pedestal and gave her everything, did everything she wanted and tried to please her 100%. From lots of little things life going to Costa to get her favourite coffee on a Saturday morning before she woke up to doing housework etc. She kind of took this for granted but also she put a lot of work into things that I took for granted and didn't care about either. In retrospect I regret that. She was definitely very controlling and very temperamental. Initially I was fine with this and basically knew no better, after a while this was exhausting and I wasnt able to maintain it and really disliked it. Everything was on her terms.
I think she destroyed our relationship when for childcare reasons she moved her family into the house for 18 months (all speaking a foreign language - but very nice people - just a lot for me to take). I avoided being in the house. Then I had a lot of stress at work (so 3 of us left the company due to what was happening), she didnt get it, didnt care and told me it was nothing compared to the stress she had dealt with. i turned to booze and was emotionally abusive to her. She had an emotional affair with a guy at work. We had counselling for months to split up. We had bitter, bitter rows, she attacked me several times and accused me of hitting her (which I didn't).
As I changed jobs and sorted myself out eg exercise, diet, no booze and went on a crusade to win her heart back she continued this emotional affair, speaking to this guy multiple a day, every morning and every night, sending selfies regularly. There was no physical element to it but she told me she would be happy to marry him and have children with him. He made preparations to buy me out of the family home.
Then he said his son was dying of a brain tumour, his son then died and he said he couldn't help her with buying me out the house anymore. During lockdown he committed suicide. It turned out he was an enormous walter mitty and most of things he had told her (and all his work colleagues) were total lies - it was actually like he never really existed because his lies were so extensive - for instance his son was never ill and was still alive (in fact his son found his body). Honestly I was totally staggered by this - how he managed to keep two lives so separate and was amazing. My ex had been on an emotional rollercoaster providing him with support as son was "dying".
Anyway because she wanted to keep the house, I sorted out finances to enable that to occur (despite her not being able to pay the mortgage in her own right). So now I have remortgaged the house (paying £10k of early repayment charges), to take half the equity with me to a new home whilst remaining on the mortgage so she can continue to live in the house with our son.
But now she has decided she wants to try and save the relationship. I struggle to get past the emotional affair, our sex life has been basically non existent for years, we don't really enjoy each other's company that much anymore, we dont have bitter rows any more because largely we dont have the energy.
For my son's sake should we try again or just move on her and let each other find happiness with other people?
