I've been going on some dates with girls that I matched on dating apps. Some of the dates were good, some not that good, but it happens. Lately, I was having some thoughts about what I am really looking for, since I guess I haven't fallen in love with any of those girls. And I feel that I don't want to develop some kind of a romantic relationship with those girls.

This might sound stupid and rude, but let's say I went on a date with a girl that is 7/10. She was nice, date was good, but deep down I have doubts about starting a relationship with that girl. I am not sure what it is, but as I was thinking about it, it might be that I hope that I might be able to find a 10/10 girl, even though it's unlikely, and as Dr. K said, no relationships are perfect.

If I fall in love, will it be different? Would it be like the 10/10 feeling?
Should I just "try" the relationship with a 7/10 girl to "test it out"?

I don't wanna be a jerk to them, as I am scared that if I date them I would find someone "better", which would put me in a bad situation (break up, FOMO).

I know one date won't show me much about the other person, but I hope you understand.
