I know and I don't really. My ex who's the reason I'm even writing this thought he could, and I told him to eff off because it wasn't fair to me and to no one else to be used when all they ever did was be there for you. It sucks and but I realize the truth now.
@electric goat...uhh no actually. And I didn't say 'random' people. People I have known forever not only take advantage of me but everyone else as well. And if being nice and helpful makes you usuable then that's pretty sad.
People don't just pick random people to use. There's something about you that seems 'useable'. You must be doing something that makes people think, "I can walk all over her."
They shouldn't be using you, but it's not entirely their fault.
