7) Text him when you’re out with your friends.
I’ve heard some really bad stories about guys who are insanely jealous or don’t “let” their girlfriend go out with friends, and especially with other guys. While I understand the apprehension, a man should be secure enough in his relationship (and trust his girlfriend enough) to not worry every second she is out without him.
If you have a man who is mature enough to tell you to go have a good time, text him every now and then during the course of the night just saying hello. It will make him smile and let him know that you’re still thinking about him when you’re out.
