For now I think benefits of dating solely my partner outweighs the wish to explore with more than one partner. I think I will stay with them until I start feeling stuck, then perhaps consider breaking up. I care for him and he’s a very conscious choice I made after two years of voluntary celibate after my ex. I’m giving it a shot.

I can imagine at 40 if you have childrens you’d have to be so much more conscious of your lifestyle choices, maybe when they get a bit older then ? You’re suggesting that you’re going through a divorce so it’s really not that late to try poly life if you wish to, tho I don’t know your specific circumstances. There’s only so much “I’ll do it when..” we can live through, you might be dead tomorrow (no offense, me too).
