Excilente that's very sad, and almost the definition of romantic. I am a softie so yes it brought tears to my eyes!! : ) (no really) (yes I'm that daft)
It does indeed feel like the worst thing in the world (agree being a bit dramatic but ... feelings are dramatic!).
I'm not even sure if it's always that sensible. Because there can and very likely will come a time in the future when you'll regret not having had that colour in your life. It's a pity if a place for it can't be found.?
But then again, disruption to the rest of your life isn't worth the risk.
I think that in a true connection, anyhow, it's like you see and feel and live your whole lives together in a matter of moments. You have a glimpse through that door and if you really are in synch, you know what kind of heaven that would be ... not to have to explain yourself, not to have to excuse yourself, to start from the same footprint and just take each other further and higher and happier than you would go on your own.
When you meet someone like that, or they find you, it's so easy it's almost funny. It's a delight. And you reflect that yes, bloody hell, all that time you'd been feeling a bit disconsolate and dissatisfied and sad and like why is this so hard with him/her/whoever in the past, was because you were right all along ... it absolutely is possible for it not to be that hard, or that uncomfortable. It is possible to click with someone such that every conversation feels like live choreography between the two of you, because you're just on the same page, naturally.
And yes, deciding that it's better to let that go and not give it oxygen is very sad. Crikey I can taste those salty tears again now so better be quiet! : D
Just a thought, though: if two hearts are getting broken anyhow, maybe worth delaying it until after the two years of bliss? ...
