Is it ok to get pissed at girls for stuff they did when...

[KappaSigKGB]

I did my fair share of partying last year, and often I would invite girls who were either friends, or that I was attracted to over to my house. Most of the time I would drink more than them, but always stay sober enough to make sure they were ok and that no random dude tried anything with them. Anyways, a lot of times, these girls would either get really sick and I would take care of them, or they would really piss me off by getting too flirty with guys right in front of me knowing that I liked them. The next day, usually I would get apologies, but is my anger/jealousy unwarranted just because they were drunk? Also on the same token, a lot of times girls will say things, and get all lovey dubby on you when they are drinking and then the next day either forget it happenned, or pretend it didn't happen. Sorry for being all over the place here, kinda just looking for some insight.
