I am in great need of advice over a dilemma causing me much emotional turmoil. Apologies, but a lengthy post is needed for context.
I am a male, married to my wife for almost 2 decades, with 3 teenage kids.
I married for the wrong reasons. My wife and I had a rocky first couple of years together with her breaking up with me and getting back together numerous times. I then ended the relationship for the one and only time, when trust issues she had with me became intolerable. We were apart for several months, but she pestered me relentlessly to get back together. I also experienced pressure from my parents to hurry up and get married. I wasn't very successful with women generally and I came to the conclusion that this may be my one and only opportunity to marry and have a family. I therefore relented, we got back together and eventually married.
Over the first few years of our marriage numerous issues arose. Apart from when trying to conceive, sex all but dried up completely. Attempts by me to instigate it would be rejected the vast majority of the time to the point that I gave up trying.
We were on completely different pages when it came to parenting and she would challenge me over it in front of the kids. A major issue was finances where my wife proved to be completely incapable of managing them responsibly and despite a reasonable income we are never able to save any money. It was not a happy marriage at all.
Then my wife developed a number of health conditions and over the course of a few years became severely disabled. She has depression & anxiety too and often talks of ending her life, with more than enough strong medication to hand to do so. We have carers attend but I have also become a carer. I have to do everything in the house, help her dress, take her to hospital appointments and push her wheelchair - the only time she ever leaves the house. I have to deal with all her paperwork / phone calls regarding benefits etc, which she finds herself incapable of dealing with. I take the kids everywhere. On top of this I work full time and do a couple of volunteering things too.
I have certainly not been in love with my wife for many years and I'm not necessarily convinced I ever really was. I do care about her a great deal and love her like a family member.
A few years ago, I started having an affair with someone nearby. She is divorced. We fell in love with one another. I managed to get little chunks of absolute happiness in my life and we both accepted the situation for what it was, but hoping one day somehow we could be together properly. However, over the past few months, my new partner has been gradually persuaded by her friends and by her now older children to end our relationship as the nature of it was now making her kids uncomfortable and the lack of a future for it with the status quo. She ended it with me a few weeks ago, but insisted that she still loved me and would still want to be with me if the situation was different. My heart is broken.
I am absolutely in love with the person I have had the affair with and cannot bear the thought of life without her. I am utterly, utterly miserable, as was the case before my affair, but then with no belief that anything better could be possible. I have for the first time begun to seriously contemplate leaving my wife. But how could she cope without me and would it lead her to take her life? Would the kids ever forgive me?
What should I do?
