As silly as this is to me, I'm not surprised because my girlfriend has helped me gain a little more knowledge of the female psyche.
Now, if your "man" doesn't know any better, he's going to try to tell you why you shouldn't be angry or upset at him or the situation, which in turn may just make you angrier. This is simply because men think with logic, and women tend to...well not think so much as feel.
Just keep this mind, should these events occur.
But really now, since you're already aware of the fact you may be overreacting, I say you suck it up, and think of solutions to how he dealt with the situation. And suggest him use them for next time. Because it sounds to me he tried to think of erroneous excuses for you not to go, when he should have been a little more honest.
