Have you ever been in the situation where you find the other person attractive, have loads in common, you love so many things about them, but, there's something missing?

I’m going through that right now. Everything else is there; attraction, love so much about them, emotionally feel close to them, but, the spark just isn’t there. I was willing to give it a shot thinking that something was bound to happen, but, it hasn’t. I mean they’re a good f@cking catch.. It’s weird when everything else is there….
