I also think a lot of this regret is coming from reality dawning. The heady days of an affair mean caution is thrown to the wind and the future and repercussions aren’t considered. Now you have woken up in your early 50s without a loyal, loving husband who is now an EX and has moved onto live the life you think you deserve.
Unfortunately decisions have consequences. I have always been heavily affected by my hormones, suffering a few days severe depression (that made me think I was losing my mind) with my cycle until I went on the pill in my early 40s. I recently had to take opioids for severe pain due to cancer. When I was coming off these and my brain was readjusting (after 3+ yrs on them) I went through a manic stage and was restless, agitated, thrill seeking and very horny. DH got pretty worried about me and spoke to me about my behavior because I was spending way, way too much time in a social media group. I wasn’t doing anything sexual and wasn’t having an affair, but I was talking to a guy much younger than me online constantly. DH asked me to stop and to shut down the app, both of which I did as I realized it was a coping mechanism and I was hurting my husband. We refocused on our marriage and getting fit and healthy and recognized all the stress and fear we had gone through with my cancer diagnosis and treatment.
What comes to me is that we have been married 26 years and are very happily married, but in any relationship there are years and times when one or other partner isn’t getting their needs or wants met all the time, work is tedious, you are sleep deprived, the kids are demanding etc. etc. There are constant small and large sacrifices you make because you made vows to the other person and ultimately you want to stay married more than you want to focus on yourself. My husband has a job and status where he could easily have affairs and get attention if he wanted to. In fact I have had two “friends” who threw themselves at my husband and made passes at him, both times he turned them down. I think they both thought I wasn’t good enough for him.
So both partners get temptations and opportunities throughout marriage. Your DH I’m sure had plenty of times where he would rather not have spent the day working hard doing something tedious to help provide for the family.
I just can’t accept the “It was the menopause” excuse. I appreciate our hormones can do a number on us, but they don’t cause as to immediately have another man’s dick in our vagina, that takes active planning and if married, deception.
I went on HRT after I recovered from cancer and was no menopausal due to chemo. It has made me feel like I am in my 30s again and our sex life has definitely benefited. We all have times of needing to reinvent ourselves in marriage.
You realise now that when you were bored and at a crossroads as an empty nester and menopausal, having an affair was one of the many options you could have chosen.
The thing is, you are talking to an audience of women, many of whom have been in your shoes and were/are also dealing with the menopause but they didn’t burn their marriage to the ground.
I am not judging you as I haven’t lived your life but you ultimately got the huge change you were looking for - the end of a long marriage.
Its time to accept your new reality and move on from here. If it was the other way round, I doubt you would be willing to take your husband back.
