I have been friends with him since teen years and I am now approaching 30. We have always been close, have known all of his ex partners (vice versa) he attended my wedding, was a massive support system to me through a traumatic separation/family court and continues to be through everything - whilst also spending most of our time laughing. I speak or see him at least 5 times a week.
He is very tactile, with lots of people. For example, would hug and kiss the cheek of all friends etc, so it's not unusual when he does these things to me. But this weekend we went away with a few very close friends and his behaviour towards me was noted by them as inappropriately close i.e. in the morning he always greeted me with a cuddle and a kiss, we spent the entire time together whilst everyone else did other things, there was not one moment where we grew tired or bored of one another. On one minor occasion he irritated me slightly and he profusely apologised and went above and beyond to make me feel better (although I was over it very quickly!)
I have always found him attractive, but didn't 'fancy' as such. I have questioned fleetingly before whether I was in love with him but felt these subside somewhat if I was seeing someone/with time. But I would say for the last 6 months it hasn't wavered at all and I think about him constantly.
Complicated because he has a girlfriend of two years. They don't live together, have only exchanged 'i love you' in recent weeks when they went on their first holiday together. He has made clear to her repeatedly that they want very different things for the future and that he isn't willing to change his mind on those things - yet they remain together. They live quite independent lives so I'm not close with her and only really know her from what he says. At face value, she is lovely but I am aware that she is slightly uncomfortable with our friendship (I have no idea what he relays to her and I don't blame her, I would be)
This weekend he repeatedly told me, albeit a bit pissed, that he loves me - this is common for us, but added that I am the only person he can spend untold amount of time with without feeling like he's going mad amongst other things.
I feel really sad and a bit lonely now because I would never want to harm the relationship he has with his girlfriend, but selfishly, more importantly mine and his. He is so special to me and I can't imagine life without him but I think this will cause me emotional damage if I'm forever wondering 'what if'. I don't know if it could realistically work anyway and I'm pretty sure he doesn't find me attractive (all his gfs have been very similar in aesthetic and personality, plus he is quite a catch himself)
I also am skint most of the time, a single mum and very high energy. He's successful in his career, free from responsibility and has hermit tendencies.
It feels like my only options are to tell him I love him and potentially destroy our friendship, or remove myself for a while so that I don't get hurt and hopefully the feelings dwindle...
Has anyone been in this situation? Any advice? I'm so confused!
TIA!
