Will my love ever settle.

My fiancé has serious jealousy and insecurity issues. We are on again/off again. It’s wearing for sure.
He is January 2nd 1972 and I am September 16th 1963.
Love has never been a problem for us. He has a past of being cheated on and has a job that requires him to be away from home a lot.
Will we make it? Is their hope?
