Can we overcome all obstacles and issues in marriage. Can we have a long lasting marriage?

I am a Monkey 1969, and my husband is Sheep 1967. We are having some marriage issues presently. I have extramarital but both try to work out as we want to be together . But he can't forget my past and recently met a woman think she is pig based on her age at 44 this year. Can we still make it up for each other and be together as husband and wife.
