Hi yeshivabochur123.
That is part of the territory. Kinda accept there will be silences and try not to sweat them. She also may feel the same about the silences.
Just know it is normal since you are getting to know someone new.
It is always good to maybe look around and comment on something going on in the moment.
Maybe make believe you may have just seen a UFO and then move into if she believes in UFO’s and life on other planet. It may sound silly, but the point is, I guess, to spend time and see if you both can grow closer in time.
Think of some things that are interesting to you and prepare some questions ahead of time based on those things. Expect things to be choppy and know it’s ok. And if she works with you and you see she is also wanting the conversation to flow, that is a good sign.
Hatzlacha!!
