Lovelife and career

Hi. Im kris born on dec.13, 1986, my girlfriend was born in nov.10, 1994. Ive been searching our compatibility both the chinese zodiac and zodiac signs. I am tiger and my gf is dog, i tried the our love compatibility here in it says we are 90% compatible. But, what I know is in the zodiac sign, sagittarius (me) and scorpio (my gf) do not really get along just like how my parents ended up, they are now separated. I also want to know if I will have a better job now since I left my job last 2013. What will I do to keep my love alive or will i find someone I think would be much compatible? with my job, will I get hired in big companies that will pay me well? please do help. Im just really confused now with my lovelife and career. Thank you...
