Men and their periods

I swear men are far more moody than women are. They have good moods followed by bad moods followed by irritable moods followed by sad moods until it loops back to good moods again. Keep in mind this cycle takes palce in about a two hour time period. never once has a man known when my own period is and yet I can tell you exactly when a man begins and ends his. The guy that I have been talking to is so up and down that I can't understand him anymore. You figure I'd be used to it but this has only been occurring recently. It is confusing me so much and I am not sure what side I should look at and take a real, true feelings. I mean, emotionally, he is semim-unstable, and I guess I knew that, but in terms of feelings he is a roller coaster. One day he likes me more than anything and wants nothing more than spend the whole day with me and the next day he is stand-offish and moody. It's hard for me to keep up and yet I will do nothing more than continue to try over and over until things work out for the both of us. I can't help the fact that I care an unbelievable amount for this boy and he will always be important to me, even if in the end it doesn't work out. Until I find out whether or not it will work out, I guess I just have to put up with his PMS. Buckle up! This roller coaster doesn't look like it's stopping anytime soon...
