Stop looking for the spark!
I used to be guilty of trying to chase the "spark" and I thought me and a date wouldn't work out because I didn't feel anything. The spark should not be a benchmark of compatibility. Yes, sometimes you get a spark immediately, but other times you don't and you may get it later on. Sometimes you simply won't get the spark but you do get a feeling that you want to be with this person as you learn more and more about them.
I think the spark is something that is emphasized way too much in rom coms and probably why I believed in it for so long.
I had to re-teach myself that the spark is not an indication of compatibility with someone and had to give dates that I didn’t feel the “spark” with a chance.
