I got some questions for you:
was it a love marriage?
what kind of work you do ? by any chance are you in some artistic field?
are you a hard-core romantic?

Mercury represents the house of separation and Saturn marriage. Therefore it is likely that you will be separated in the major-period of Saturn. It continues till Oct/2022.
