Des,
Did you do anything physical with this other man? Or were you just considering it? I guess I don't know the history. Having been somewhat in your situation, I can relate to what you have been/are going through. Please PM me if you need to. I do not have children, but I was at a point, years back, where I felt "old" at age 24 and, like you, wanted my youth back- and to me, a new "spark" seemed like the way to feel young again at that time. I had been with my boyfriend/fiance (now husband) for 6 years. I did go down that road and have regretted it deeply ever since. I can't say I didn't learn anything because I have- I learned that I never again want to hurt the person I care most about, who has always been there for me, just for a bit of feeling "free" and "young"- it's not worth it. But it seems as though you are figuring that out for yourself, however you got to that outcome.

As for telling him- I guess that depends on how far you took it? Many would say that people relieve themselves of things for selfish reasons- to alleviate their own guilt. I have to say, I did that as well. But I also have to say, it didn't work. The guilt didn't go away, but I certainly did cause a lot of hurt and damage. That's not to say I'm not glad that things aren't out in the open, but just that there are pros and cons to telling. Again, I don't know what all went on, so that's for only you to decide. But I would definately suggest that if it was just a temptation, he probably doesn't need to know.

That's just my personal experience and thoughts.

Good luck- we wish you the best!
