A lot of couples are unequally yoked and some believers are not compatible. In the world its selfishness, boredom no patience and not willing to endure anything in the marriage. This is expected because they do not trust God. Christain marriages are falling for the same issues as the world. With God in the centre and glue in your marriage you should withstand any storm. Even if you fall out of love or you feel you are not compatible anymore GOD can help you to bring that fire back amd you can start growing together in your Goals and dreams together as a couple. It is so easy and acceptable to get divorce or separate these days.. being married is still the right thing to do..
