<human>: Give me a shortened version of the text

For the sake of brevity, this will be as short as possible. Together for 4 years, and what the title says, she does not communicate well. In the past she has gotten blackout drunk a few times. One time she slept in the same bed with another guy but never told me. Also she goes to parties a lot and sometimes she gets blackout drunk and dances with other guys. BOTH times her friends were witnesses say that she initiated the dancing and some say she did not. Point is, she never tells me any of these things while in contrast i'm totally open with her. I am really hurt how she will not tell me any of these kinds of things. I can guarantee that she did not "cheat", but to me these things are still important.

I view these acts as small things but I am just bothered that she tells her friends every little detail about them but leave me completely in the dark. Am I being unreasonable for wanting her to tell me these things? I feel that I should be cautious with her now. I do not want to be so devoted to someone who continually "hides" things from me. Should I just give up and not care that she wont tell me things or is this a bad sign? Any advice is most welcomed.
<bot>: How do you deal with not being told that your SO dances with other guys/girls and gets backoutdrunk in the same bed as someone?
