I've always gone out of my way to be nice and respectful and kind to my bfs family but what do i constantly get for it? Shit talked about me behind my back. No more nice custom christmas and birthday gifts, no more baked goods, no more friendly chit chat. I am done trying if this is what i get. So sick of giving to people and getting shit on in return.
