Son in-law control my daughter

You should give your daughter more confidence. She should become more active to control her life. The prediction shows that the situation would change into a better situation next year.

Your son in law is a Tiger and Sarah is a Rat. The star sign is not very compatible. Your daughter will always have to yield to a Tiger demand they must work together for a good relationship, this should be a give and take. But if its only taking which your son in law is doing and won't change, then separation is the key. They need to communicate more with each other for things to work.
