Well. Update.
Under the tension of the situation the GF and I started over analysing everything we said to each other. Time spent together not in bed was not working well, things started cracking between us and between me and wife at home. Then about 6 months ago, wife found out, and gave me a choice. I chose her. And things worked very well for a few weeks, more effort on both our parts, and it sometimes seemed as though she was enjoying the intimate side of things. But then it all stopped again. No sex, few hugs, a boring passionless life. And huge pain to the GF which she did not deserve.
So now I have to think about what to do next, as I don’t want to spend the rest of my life like this.
Time to move out and have a “trial separation” ? How do you say this to someone in a kind way?
Nothing other than abuse expected here. Just thought I’d update the story.
