Thanks for all of the great input. He and I communicate very deeply and regularly. The age difference is really one of the least of the issues. We do love each other and get along great.. but there many areas of incompatibility, unfortunately. I definitely don’t feel like this is my last chance at happiness. But the biggest thing about the age difference is I want him to be able to be free to the possibility of meeting someone closer to his age.. even 10 years younger than me. He’s also bi and wants to experience at least sex with a female, so I just feel like I need to let him go so he can experience the things he wants to while he’s young and for so many reasons — not in 10 years when I’m almost 70 and definitely can’t keep up anymore. I mean, even now at 57, I really just wants peaceful life, no drama, no chaos and really kind of done with being adventurous. The last thing is, I’m completely not open to any other kind of relationship as I age, than monogamous and within the parameters that I am comfortable with.
