That was actually why we fought that often. I do believe that im the protective type of boyfriend. And what concerns me the most is that, she drink with her buddies at someone's home... Yup, male buddies....
Oh i seeeee I thought she'd drink at a club/bar but at someone's house is tricky. Probably she doesn't want to bring uninvited guest.. so probably she'd have to give others a heads-up if she brings you along. Does she not have female drinking buddies? Maybe you can suggest her to have a female/non-male friend if you can't go either or have her ask her male buddies if they're cool with you coming along. I really don't think they'd say no but if your girlfriend says she's not willing to ask then I'd definitely be uneasy. If you come uninvited bring extra drinks maybe >.<"
What is her age?... *suspicious* Ha? What difference does it make? We make acquaintances and friends every day. If she was having a nights out with other girls where men aren't allowed that is one thing, but it is nothing odd about who are in a relationship to spend time with each others friends. Weed is less harmful than alcohol, so other than legal implications its not a big deal. As long as they don't use anything more dangerous than that. I think you should just ask her what she truly wants. This way you aren't trying to guess each others intentions. Being overprotective isn't exactly a good thing, but most important is communication. Last but not least, get a cat, treat it as your master.
Male buddies -> You can't tag along? That flag isn't red, its crimson. Does she deflect questions? Do you have reason to be suspicious? Does she abuse Ultimatums? Does it seem like shes trying to hide thing? I've seen alot of women cry and never change. Whatever you decide, goodluck man.
