Its the first night I haven't gotten to see him.
You are right. Men and women are so different. We look for signals all the time, guys are like "what's the big deal?"
You've been dating for a few months now. That's a long time to not have a "night off." Maybe he just needed to be alone for a night. Not because "of you" but people like alone time. I like mine and I know hubby likes his. We still love each other dearly.
I think it's a good thing. Abscence makes the heart grow stronger and all that jazz.
Him missing you is not always a bad thing either.
