Should I (F18) keep talking to this girl?

I met this girl (F18) on tinder and we’ve been talking for a week and a half. She’s nice and I think I like her but I also think i’m bored. I sometimes wanna just stop responding but I never do because I like the validation and I get butterflies when she texts me. I feel like if I stop talking to her my life will go back to the same old boring ways it was before. I do think I like her but i’ve never even met her in person. It’s the fantasy I made up in my head that I like. If I just waited for her to get bored and stop responding to me, i’d just feel rejected.

Should I just rip the band aid off and make an excuse to stop talking to her? Or should I keep talking in hopes of it going somewhere?

Edit: Mixed up our ages. She’s 18 i’m 19.
