In march a casual fling ended because he wouldn't upgrade it to a relationship. We tried just being friends but I couldn't make the transition and in the end I deleted his number etc and went no contact as he started to mess with my emotions. This morning he text me wishing me a happy Christmas. It wasn't a round Robin text as it was personalised. It made me cry hearing from him as I'd kind of boxed up that time in my life as it was an unhealthy - but amazing - thing we had.
I am a nice person and feel that I should reply but then I wonder if he deserves it?
