Years!!! Dude, I think you had a fantastic run with them. And you should be happy to have found MLs you could clicked with so well. But as all things go, good things will come to an end. And it could be for a variety of reasons - she found a boyfriend, personal issues, exterior influences, or maybe the arrangement just ran its full course. But whatever it is, look back at those wonderful years, smile and move forward excited by finding potential new replacements!!.
My average interest in a worthy ML is usually just a few months. And then I will switch her out of my regular rotation roster.
The longest ever ML I was seeing was for 2 years. We did everything. It was always wet, wild and wonderful. But we both somehow knew the day would come when we will run our course. One day, after another glorious sweaty session, for some reason, I didn't pre-book my next appointment, which I usually do. She also didn't ask. And we just left it as that. No more texting. Perhaps one day we'll pick up where we left off. But for now, we're both moving in separate directions.
The only other MLs presently that will see a very extended period of time in my regular rotation roster is OG Angel, Cheryl (but she's leaving soon sob) and MM (hope she doesn't leave soon lol). I think by next month, except for these 3 fabulous MLs, my entire rotation list will change again. Hahahaha.
