6 years in the LS with zero jealousy and now suddenly Im getting jealous at every meet, is this an aging thing

46f married to 48m, weve been in the LS since 2018 with basically no jealousy issues until the last 6 months. like genuinely none. we used to be the couple our friends asked for advice bc we made it look easy. then around the start of this year I started getting these waves of jealousy during meets that I had never experienced before. last meet I literally had to step out of the bedroom for a few min bc I felt like I was going to cry. nothing happened that should have triggered it. dh was being completely respectful and lovely as always. nothing has changed in our marriage that I can point to. kids are fine. work is fine. we still have great sex. but my body is responding to LS situations differently than it used to. my best guess is hormones?? Im around the perimenopause age. is this a thing?? are there other women in their mid 40s who suddenly became more jealous in the LS after years of being chill?? did it pass?? did you have to change how you played?? would also accept "no its not hormones, your gut is telling you something is off" if thats what you think. but it really doesnt feel like dh is the issue, it feels like Im the issue and I dont know what changed.
