OP needs to clarify the question:
Ladies night once in a while (eg 1/month) =
Girl going out almost every weekend without you = plus if thats the case why u with that in the first place..homegirl come back smelling of peach schnapps and finds you fallen asleep sucking ur thumb with Lifetime movies from the mid 90's playing
That's why she goes out in the first place because that's her boyfriend's idea of a good time. Men are boring in relationships. Forever trying to come over and sit and look stupid. Why are we in bed by 9pm EVERY day of the week?
