He started out super flirty, texting me everyday and talking naughty to me and sharing memes. Then he asked me to be his girlfriend and I said yes. When I did that, he stopped texting me everyday, said he was busy with work. He still sends memes and talks naughty, but it's less. We talk about how his job is and any other issues, but he's like boring now. It happened so fast like in 3 days. Did he not want me to be his girlfriend that fast? We haven't had sex or anything, just talking and dating.
