Reg Marriage: you will get chances for negotiations in 2019,and Ketu dasa will be good for marriage. The bride will be from a family already known to you. She will be beautiful and dynamic.
Note: In Merc period (whatever period if may be), then you face some minor health trouble. Please take care of yourself.
Be happy.
