Sir, God is not necessarily concerned with our happiness in this life. God is more interested in our holiness and our salvation.  God uses the events of this life to form us and make us holy.  We learn obedience through what we suffer.  

Secondly, as I have said before numerous times and I will say again:  NO ONE least of all myself is saying that God wants her "trapped" in her marriage.  If she is being abused, I am quite certain God wants her to get out of that situation any way possible.  But here we are talking about divorce.  Remarriage is the issue.  How many times to I have to say that before it sinks in? Divorce is fine.  Remarriage is not--not without an annulment.
