Just my opinion: I wouldn't've done it. As personal rule of thumb, I keep my neighbors out of anything pertaining to my dearest aspects of personal life. It can and, more often than not, will turn into a problem if something in the relationship goes south because once it heads that way, it only gets worse. Soon, you have a neighbor who not only knows but harasses you about it, and then tells others. And then, you're outed.
I suppose the only exception to my rule would be if I was a renter and not a homeowner; it's far easier to give notice and move out instead of sell the home.
Distance is a good initial relationship value. I'd never go for "The Girl Next Door", ever. Call it what one wants, "familiarity breeds contempt", "a prophet is without honor in their neighborhood", so on, it all adds up to a similar adage about falling for a co-worker: "Never put your honey where your money is". If I ever did 'fall' for someone, they would have to not live anywhere near me; should the relationship grow to a point of commitment, then we'd move in together, but if it failed, we'd still have the benefit of distance to keep things from getting too sour...unless the other person is a vengeful, sociopathic menace and you'd need to file a restraining order to move on.
There are some aspects of life which don't lend themselves well to convenience and are worth making the extra effort for. Again, it's just my .00000115 Bitcoin. But despite my opinion, I hope your experience is an exception to my belief because I do enjoy seeing success stories.
