I just been reading a book (novel) about a couple living around 100 years ago... the new wife asks her sister (pg with 3rd child), "have you hit the wall in your marriage" (a term she heard another bitter woman using... her sister's answer: "it depends on how you approach the wall... sometimes it's just a turning point." The discussion goes on, and the point is that love is not just the honeymoon and romance. It's the commitment to stick with it through thick and thin.
My marriage has not been a bed of roses... or should I say, they forgot to take the thorns off the stems! LOL. But I have reminded myself that I promised God and my husband that I would stick with him through sickness and health, poverty and wealth. Immigration can take the mickey out of you, and kids can take the Minnie out of you, but if you stay committed to each other, you can make it through anything. And I personally think that if we keep God as the third strand in the cord, it will be strong. (I know not all share my viewpoint on that, but I don't think I'd make it through what we've been through without God in my life).
