Candlelight, my SO wasn't cheating while we were actively dating and being intimate. He started seeing less and less of me, and I had a feeling he was seeing someone else. I think when he was ready to take it to the next level with this woman he had met, he felt obliged to break it off with me. He said he "wanted to be honest" with me. Since he was my best friend for so long, I still consider him a friend. He's not seeing anyone now and has been calling me. However, it will never be like it once was.
Now, in your case...if I were in your shoes...I would just hang up on the man when he called. But that's me. You don't deserve to be treated like that.
Thanks for the thoughts, John.
Hugs,
Connie
