Now what I do with girls I’m friends with, is that I stick to strictly calling them. Calling is so much easier and straight to the point without any fluff, and you’ll become much better friends as well.
If you don’t go home with her, you’re still considered a random.
Anyway, when you text her the next day, she probably doesn’t remember you.
This works especially well if you actually did make out with her and she remembered it. After that just continue with a flirty conversation but do not say anything about hanging out. You’re going to do the opposite and make her wonder if you’re really interested in her.
She will feel less cool than you, which is ultimately what you should be aiming for. Tell her you think you met her at the party last night. End the conversation and text her something random the next day.
Also, you can text her every once in awhile about stuff YOU are doing.
