Marriage

One of the advantages of being married is that, when your spouse is overburdened with problems and has trouble praying, you can pray their prayers for them. "... a man shall ... be joined to his wife ... and the two shall become one flesh. So they are no longer two but one flesh." (Mark 10:7-8)
Of course, it also means that when one suffers, so does the other (but married people already know that).

And remember...
Love is a gift, given freely, given completely, expecting nothing in return.
Love is wanting to do things you wouldn't normally do.
And Love is a choice.
