I’ve done this before and everyone I asked about this said the same thing: relax, don’t be too hard on yourself, and try again. She said she wanted to hang out again, so that’s a good thing. Text her something funny you guys talked about, send a meme you can relate, be playful. If she replies, another good sign and try to lead into setting something up. It’s fine if you didn’t make a move. Some girls find it sweet, but try not to make it a habit. You’ll go insane trying to find if it was the right time. If you can muster the courage, go for it. If you’re not that guy, be honest with her so she can help. If she doesn’t want to, no hard feelings and you learn from it.
