late forties... opening up to save 22 yrs of marriage, are we daft

right brace yourselves. me and the missus are 47 and 49 (dublin), married 22 yrs, two kids nearly out the house. last 6 yrs have been a slow slide into roommates. weve tried date nights weekends away therapy supplements (ha) the lot. last month she said "ive been thinking, what if we tried the swinging thing" and i nearly fell off the couch. but the more we talk about it the more interested i get. but also we are not 27. were not exactly the demographic flooding the clubs. is opening up at our age realistic or are we going to feel ancient and weird at every meetup. and is it daft to think this could actually rekindle something that died 6 yrs ago
