I need some advice here. I went out with a girl three days ago for the first time. We had only known each other for about a week and a half before, and I texted her how her knee was (she hurt it when we went out snowboarding) the day after. I probably should have called, but we ended up texting for about an hour after I sent the text. She's 18 years old and in college. The day after (yesterday) I didn't call her, but she texted me to see if I wanted to go out again with her and her friends. That fell through and now it's today.
I'm going snowboarding for the majority of the day, but should I send something to her anyway? I don't want to seem creepy, but I also want to let her know I'm interested. Also, should I send her a small generic "happy Valentine's day" text tomorrow? Or let that be since we've only been out once together? I like her, but I'm not convinced that she definitely likes me yet.
Thanks a lot!
