Capricorn girl, scorpio boy, love-hate relationship, help?

I've read about capri-scropio match and they say its a really good one. when we arent fighting, we are soooo in love and everything is so perfect, and i believe we can have a strong relationship and marriage. when we're ok, hes very sweet and loving and wonderful to me...however, when we fight, it terrible. our strong characters clash...by talking to him so much, ive picked up a lot of his scorpio qualities. it gets to the point when we both wanna break up, but neither lets go. Its been 2 years now, we want to get married. we're in a long distance relationship. being a capricorn, i am very patient and tolerant, but he's hurt me a lot in the past verbally, emotionally and even something else. thats makes me think, when we fight, i feel like i tried my best and want to give up..maybe we're just cranky cuz we havent had in a year . we do communicate a lot. i do tell him how i feel, but we keep fighting. when we're not, we're so perfect together, i feel so so happy,but he makes me really depressed when we fight. with a scorpio, life is russian roullette, you never know when you'll get the bullet. the love is intense, but the hate is just as intense. life with one seems risky, dont know when theyll snap. i dont know. im tired of trying to please him, iive moved mountains for this guy, trust me ive done ALOT and now im tired of feeling like this.im a capricorn, so i give it my all, and keep on trying till i achieve something, but now im contemplating giving up because im losing faith in him.....how can i salvage this relationship, or what do you think should be done on my part? please be respectful...thank u in advance
