I had a great ATF for 8 years but she finally just flipped out and I had to move on. I went crazy with 2 girls a day for 6-8 months to get over her (yea, I am a softy) but I finally had enough sex where I could think clearly again.
It is so hard to find someone you feel comfortable with and enjoy not only the sex but actually talking to them. I have found a new favorite that has settled me down where I almost feel I am cheating on her if I see someone else but I am happy again and finally over my previous ATF who was crazy!
I enjoy the comfort level with a favorite.
Hang in there - you will eventually find another favorite but it does take time.
Happy Hunting!
