I was on tinder wasting time and I got a potential date by mistake.

I told her that if I'm not busy this weekend I want to go to a park and she should come with me (she said yea and gave me her #).

Since it kinda fell on my lap I thought why not go out. I'll message her tomorrow to let her know that I'm free Saturday.

My question is what happens next? Does it matter if I don't text at all? The weekend is quite a ways away.
