Hi ya Shy, It really sounds like you both have a good relationship overall. Especially if you can talk to each other for hours on end like that. I envy that and most people in relationships dont have that kind of communication.
It is fustrating to cry like that, sort of like and emotional burst...is how I think of it. I sometimes get like that a few days before my cycle. It can either come out as being very emotional or just being plain angry at the world...lol! Maybe, if you know that it is "one of your days" you could try to regulate how much you drink or just have one or two beers. It would seem that the combination of alcohol and the increase in hormones at that time played a big part in how you reacted to what was said. No one knows you and your body better than you...what you can and cannot handle. I think it is a matter of recognizing what the triggers for it were and trying to avoid them in the future.
