so last night I got really depressed because my fiancé and friends went out and I couldn't go because it was at a hookah bar. Now before my fiancé left he asked if I was fine with him going , and I was but as the time passed I got sad, not because I couldn't go out and party with them but because every time they choose to go out its to some where I can't go. and I was just depressed about it.
