Hey yall. Am in college right now and I have a question though... Is a girl not interested when she declines to hang after a few times? Like I will message her

Me: "Hey whats up" Her: "Nm you?" Me: "Just got back to my place from the lib. You trying to chill and watch a movie?" Her: "Im too tired!"

That was a conversation from the other day and I left her on read. I feel like this happens too often. The girls that I have fucked I met in person at a party, proceeded to go back to my place and fuck for a few weeks. My texting game only worked once and that was because I have already fucked her. I can never to get a girl over that I have not fucked before.

My question is, are they not interested when they decline to hang on a random weekday evening with an excuse like they are too tired?
