How to let go of your ATF
So I've been seeing this woman for 6-7 years. She's in her late 30's early 40's, me breaking into my 60's. She's still attractive, has a nice bod, is very smart and has her own burliness, and is very amicable and has never said no to anything I asked her to do. Problem is she apparently doesn't cut it for Jr. Anymore. I don't know if it's me getting older or if it's the familiarity factor or something else. With her, Jr. Does wake up, puts out a valiant effort, but in a minute or two goes back to sleep and doesn't deliver the goods. Same Jr. Is a total party animal with other girls whom I find attractive and even some whom I don't. So at this point, I just want to break if off and go seek some greener pastures, but I want to do it as nicely as possible. I don't want to leave her on bad terms or hurt her feelings.
So, my question to the esteemed members here is: how do you break it off with your ATF?
