I've been friends with a man at work for about 5 years. He's divorced with a new girlfriend (I think), I'm happily married with a 1yo.
I wrongly thought we had a really nice friendship - close, open and honest, sometimes 'cheeky', perhaps even flirtatious, I suppose sort of like the older brother I never had.
We met up at the end of July for drinks and a meal after work, and had a lovely time (it was my first social occasion since the birth). As we said goodbye he tried to kiss me. I laughed it off and felt I handled it well, I tried really hard not to make him feel bad about it and I don't think he did. The following evening I got a text from him saying I should be stronger and have more willpower (wtf?). I was a bit put out by that and he sent a couple more texts saying we needed to meet up so he could explain as he hated the thought that he had confused me. I said ok great, but every time we arranged something (at least 4 occasions) HE always dropped out at the last minute, so it never happened. Then he stopped contacting me altogether and I was just left in limbo not knowing what was going on. I had a few sleepless nights feeling really rubbish about it, then decided he was a player and not worth it and I made a conscious decision I didn't need this 'friend' in my life (there have been other things he has done which I won't bore you with, but my decision wasn't just based on this one incident iykwim).
Cut to last week when he stumbled into my office at work by accident, not realising I worked in there. I put my head down as I didn't want to deal with him or be openly rude. But he saw me and came over all friendly "oh we must go out for lunch!". I murmured something non-committal but that night he followed it up with a text saying how sorry he was that he hadn't made time for his "best friend" (why he still refers to me as that when I haven't heard from him for months I don't know). I've agreed to meet him for a coffee on Friday.
Should I bother going, or just stick with my original decision? If I do go, how do I play it? He can be a bit 'oblivious' and I do think he won't even realise how he's made me feel this last few months.
