Ox man and rat woman

My lover is older than me he is born 17.03. 1961 and myself 15.05.1984 but i feel he is my soulmate,lately from 6 years working with each other something makes us so near and confessed to each other about love only from 3 month ago.
I feel so safe with him and totaly understood without even talking he can read my mind without words.
Can this relarion last and end with marriage?
