How did it not work? leo/sag rising and sag. (don't know rising)???????!?

Well lets see, at first it was GREAT, he gave me attention and told me nice things, held my hand in the car and stuff, the things that make my pion burn, and he was OH SO cute, and i made sure to tell him. but then he moved in with is sister, and after that everything went down hill, you see my dad is a Saggi too, and his outlook on life is SO gray, and life's hell, and so was my man, his day was sh!t, and so mine had to be too, then he asked for some "time" i gave it too him, didn't call, didn't do anything. and then i went over to hangout with his sis, and he came home he said sorry and we were "lalala" or whatever again, the next day its like "what the fck do you want" and the crap-asz attitude again. so i left him alone, didn't talk to him all day & then so pretty much we broke-up, why? weren't we supposed to be great/ NOT WHAT I EXPECTED, MAKING ME HAVE A NEW OUTLOOK ON ASTROLOGY.
