It relates because age aside, you are having concerns about your poly nature and it's "limits" as they apply to your existing relationship(s), and so am I. :shrug:
As for the age thing - I'm realistic about it. Both girls insist that they are going to be around for the long haul; Violet has had almost a year to convince me, Anne only a couple of months to make up her mind. I absolutely get it that they have their 20's ahead of them - how would it be again, lol - in fact, there have been many conversations about me feeling that by participating in this relationship I am "robbing them of this time in their lives". Both of them are auite pointedly stating that plenty of girls marry very successfully at their age, and that if they meet that guy and he's a few years older, so be it. And for the record, the age gap is ~13 years, not 20, so when they're 40 I'll be a respectable 53 give or take. Not TOO bad, lol.
In any event, i am grateful for the time we are having, one day at a time. Every morning I wake up amazed that Violet is next to me. When we meet up with Anne, I am speechless looking at the two of them sitting next to each other smiling and saying they love me. If and when one or both of them "outgrow" it, I will have had this time and will be gratefull for it. Until then, I choose to let them make their own decisions so long as they aren't destructive, and right now they both continually choose to stay with this, and are in fact quite annoyed that I question them about it!
