Hey!
I just admit I wouldn't even go - with the benefit of hindsight and having been to these kinds of things before.
Already you are on tenterhooks right? Planning what to wear, when to wash your hair? Not sleeping so soundly, checking your phone etc?
It's a waste of time.
I dated this man a few years ago who was not a great match for me and I ended it. I then invited him to dinner about a month later. It was 'something to look forward to' and 'I missed him.' In the event, it was a waste of a Saturday night, it was pointless and I couldn't wait to shoo him out of the door - because the road led nowhere, so why did I walk down it? I wasn't going to get back with him so why did I spend any more time with him? The whole thing just made me feel sad and I wished I'd gone out either my friends instead. I will never do that sort of thing again - 'the moving hand writes, and having writ, moves on' etc.
I think that is what is before you.
Even if he says, 'I am miserable without you, I want you back, I want to go back to what we had' - the fact is that you ending it was what made him say that, NOT that it was his real desire.
'Not his real desire but I'll do it if you want' - do you want to exchange your life for that? Do you want that to be the story you tell in later years to explain the choice you made in a man, when other people will be telling proper love stories? How secure do you think a love like that will be, especially when someone who really turns his head comes along? Or turns yours?
You say you are a romantic - good. Excellent. That is right. Have eyes for romance for your own life. Do not be the chaser, the one hurrying things along.
I am getting marred in two weeks and my man is 100% onboard and in fact tells me he knew three weeks after we met. His behaviour around our relationship has never been anything less than 100% committed and I can feel that in the way he touches me, cuddles me, the look on his face when he gives me a goodbye kiss.
This man has shown you who he is, and my advice is that it is not good enough (otherwise you'd have been happy) and he is going to waste your time. If things don't work easily, don't force them. I wouldn't waste my time seeing him, getting dressed up for him etc - it will be sad and pointless, and you will have to revert back to the new life that is emerging for you. I simply would not go - and stop thinking about him, stop looking backwards, learn from what you have been through and get out there living life and waiting for a better quality love affair - which WILL happen.
