Many have divorced and remarried again for the second, third or fourth time, not because their spouse passed away, like we promised God on our wedding day, til death do us part, but we left because some of us became lazy and fail to work on our marriage. At the sign of trouble, we bail. (This is not the case for everyone.) The same work, time and energy we use developing a new relationship with someone else, we can use the same time and energy right where we are...with our spouse. Jumping from relationship to relationship, marriage to marriage, really won't solve anything. Whoever you are with, work will be required. So why not just stay where you are and work it out.
In the bible, water is a sign of life, cleansing, spiritual refreshment and God's blessing. To keep your marriage going, you have to go back to those things that made it grow in the first place. You have to keep praying for your spouse and even praying together. When trouble arise, go back to the Word of God for guidance...together. You have to continue to kiss more, love often, say "I love you", go out on dates, talk, appreciate, respect and honor each other. You have to do these things even when you don't feel like it.
Marriage is a full-time ministry and only the strong will survive. Don't be consumed with how your neighbor's marriage is or is not going. Take that energy and focus on your own spouse and marriage. If we have less competing, envy less, it will kill our curiosity and there will be less infidelities.
Your grass can grow if you take time to water it.
