So I have been with this girl having sex about 2-3 times a week for the last 3 months or so. Usually it just consists of me coming over late at night and us fucking. well recently i've noticed a bit of a paradigm shift. The last time we hung out she had invited me to go dancing. I think this is because she is tired of us just hanging in her room. Now I know to keep a plate spinning I have to keep it interesting and new. So this weekend I invited her to dinner to celebrate the end of her job. I asked. "when are you free sunday?" To which she responded "Im not" and she left it at that. This is where I fuck up. I say "when are you free? we need to go get dinner to celebrate" and then she says she is free sunday at 6 ocklock. She was kinda cold and unreceptive and changed her story to me a few times. When I asked her if she meant 6 on sunday I got no response. I know radio silence is the play here but i'm wondering what your guys prognosis is. I Could be over thinking it. But given the context of our relationship this behavior is very new.
