Whats my chances on a scale 1 to 10 winning my girls trust back, and not lossing her?

me and my girl have a problem, see i lied to her. it was just a little lie and i only did it cause i dont like to see her upset. well she caought me in the lie and asked me about it. she was hurt more than she was upset, and was in tears. i promised her i would never lie to her agin. well two days later i do it agin. iv now hurt her twice. she swears she cares for me, and i love her with all my heart. and to prove that to her i gave up my childhood dream see i work to jobs, im a deputy sheriff and i also work for the sea island company. well being a cop is what i live for,but having two jobs left few time to spend with her. well i picked her over my childhood dream. i picked her because i love her and would do anything to keep her happy. and now im about to lose her, she still says she cares for me deeply. but the trust is not there now. and i now relize how much she means to me, and its taken the verge of me losing her, to relize how much i need her in my! have i lost her for good?
