((((Direction))))

I think there's been some good advice here.

I wouldn't stress too much about the details, (height, kids etc) since anyone worthy of you will accept you the way you are. Changing yourself for another person's sake only is a really really bad idea.

Also, I'm sorry you feel lonely, but remember that having a relationship is NOT the be-all and end-all of life, even though it's hard to remember that when your mind is full of someone else.

As to the spark thing- in my experience, it's a combination of physical attraction, and a certain kind of knowledge, I guess, that you connect with the person on a deeper level. But sometimes the spark is more intellectual than physical... I had a brief relationship last year with a 35 y/o,( I'm 21) and it was more of a mental thing where we never stopped talking than a physical thing. We were friends for ages first, and I was actually really surprised when I realised that I actually liked him. We no longer date, but still are close friends. So I guess the spark doesn't have to be physical, maybe just something that draws the two of you closer..
