sounds like a situation I was in...I missed my chance. I used to try to resurrect my chances all the time once the time came when we wouldnt be able to see each other as much [which I knew was coming..], but I've pretty much now accepted that I am out of luck unless some magical event presents itself where we get to spend alot of time together again, but magic like that can't be counted on

Trust me, act on your instinct and move in, it'll be your biggest regret if you don't
