I haven't spoken to my ex fwb for 2 months. It ended because I got feelings and he didn't and he was actually quite mean to me about it all. Anyway out of the blue he messaged me on social media as I had blocked him otherwise, and I stupidly ended up going round and sleeping with him. I know he used me and I let it happen I thought I would be ok but its dredged up all the old feelings and now I feel rubbish again. Hes like an addiction I just can't say no to. Why can't he just leave me be? I know he is on fab swingers so its not like he can't get ot from somewhere else.
