What is a woman to do?

The dilemma of the week is the proper way to respond when falling in love. Now I know we all say no games, but it seems there is always a little game playing so how is a woman to do it correctly? Let me give you the scenario, a friend of mine has been dating a man for a few months, and she is “pressed”. In fact they are both “pressed”, they talk on the phone multiple times a day, email each other constantly and see one another when ever possible. This weekend they consummated their relationship (did the deed), and he spent the night too. However she immediately started questioning and analyzing everything from that moment on. Now I know we women put too much emotional baggage onto sex, but for this blog let’s assume that we do and we can’t change. I mean she did put emotional baggage on the sex act and there is no going back now. So the “day after” played out in the following way, he emailed her, she emailed him back, 5 hours later he emailed her back, she immediately emailed him back, he sent her a text message that said “Call me when you get home”. Now this exchange is a little cool compared to their previous exchanges, in addition he was cool the morning after. My friend is completely stressed that she had sex too soon, and that he is not all that into her anymore, etc. My advice to her was to not call him, wait for him to call. I thought this was fabulous advice; however another man said to invite him over that night for a follow up booty call. I think that is a terrible idea! Here she is falling head over heels for a guy and she should back up and get a little perspective. So we women need advice, what is a woman to do in this situation?
