I think I just need some hand holding here.
I've been in a 5-month-long relationship with a man I love as much as you can after such a short time.
Probably doomed from the start as he had only separated from his wife of 22 years 3 months before we met, and I had only been separated from my husband of 11 years for 5 months. Yes, I know, I know....
I'm not stupid and I don't have my head buried in the sand so I know there was a lot of void filling, loneliness avoidance, rebounding, whatever behind us getting together. This wasn't the sum total of it though - also plenty of emotional, intellectual and physical attraction.
He acted really committed to a long term relationship with me. Started getting involved in small ways with my dc (aged 10 & 12). Lots of future talk.
Over the last few weeks he has become more emotionally distant. Little things missing, like no xx at the end of texts, not calling me pet name any more, not very enthusiastic about seeing me. Swore that everything was ok, just stressed. Coincidentally (or not) the start of him pulling away was when he went off his antidepressants.
Yesterday my anxiety about his distant behaviour hit a tipping point, and I told him I needed to know whether he was 'in' this or not.
He told me he didn't know what he wanted or how he felt. Asked me to give him 2 weeks max to sort out what was in his head - basically to decide if he wants to be with me. Said he still has feelings for me.
This all comes 3 weeks before he was meant to join me for part of an overseas holiday- accommodation, flights etc all booked and paid for.
So do I treat this as a break up so I don't hold on to false hope for the next agonising 2 weeks? Will 'waiting' just delay or prolong the heartbreak I'm already feeling?
This is all such a fucking red-flag-ridden cliche, but why does it hurt so much? Was I kidding myself that things could work? Could they still work? I just don't know what to do or feel 

Thanks for reading anyway
