I was never anything more to you than a simple sex toy. It was great while it lasted but as my marriage ended and your relationship didn't, I saw that I would never be more than a simple fuck buddy. I was in love with you, you said you were in love with me. Maybe you were, maybe you weren't, I'll never know. If it was 3 years ago, I could see giving it another chance but now I'm married with a son and another on the way.
I miss what we had sometimes but now I have an amazing husband that isn't ashamed to tell me he loves me and only me.
I wish you the best of luck, I hope you find someone you can fall in love with and that will make you forget about me.
Update: I messaged him. I knew I shouldn't have but I did. He says he misses me, he made a mistake letting me go. :'( I've always loved him. I can't leave my husband! He's not asking me to but talking to him brings up all those old emotions, feelings, it makes me wish it would have worked.
