<human>: Can you provide a brief rundown of the text in within 3 sentences?

It's just not there when I kiss him anymore. I don't know how to get it back. It hasn't been there for some time, and it's only ever really been there in waves. I think deep down I was only ever so-so attracted to him to begin with. Throughout our relationship, we've struggled with sexual compatibility. 

We are excellent partners on so many levels. He's smart and objectively handsome, the pheromones are just "off" somehow. But we get along great otherwise. 

We've been together almost our entire adult lives. I'm scared of starting over, scared of being alone, scared I might be on the verge of throwing away the love of my life because of something shallow like physical attractive. I just have this constant nagging feeling.

If we break up, I want to skip town and move away. This town is too small to be his ex in. I'm sad. This whole thing is terrifying. I'm worried if I don't do it now I'll want to do it down the road and then I'll be too old to start over somewhere else.
<bot>: Can you get the spark back once its gone, or is it better to just end it now and move on before I'm 30?
