Quick help please

I'll go out, have a great fun interaction with a girl. But then just not feel right talking/hitting on another girl in front of her.

It's like I feel like I get one ser per section of a bar and then I have to move on to the next place.

Am I crazy? weird? Silly?

I could really use a new mindset on the matter. It makes me feel super awkward to go from hitting on one girl to hitting on another right in front of both.
