Is Your Relationship Strained Because You're Overly Critical of Faults?

We sometimes spend years in relationships looking for "Mr. Right" or "Mrs. Right" but we're unsure if we should marry the person we're involved with because they have a few faults. So we stay unmarried, waiting for our loved one to manifest the perfection we desire. Of course, that never happens. How can we know if our expectations are unrealistic?  If you've been dating someone for a length of time, you think you're in love, but you hesitate to take that final step because there are a few things about your loved one you don't quite like, is it possible your standards too high? We sometimes enter marriage with unrealistic expectations, nitpicking over the faults of our spouse, never quite feeling like we're "happily married." We spend the entire marriage in a state of discontent, concentrating on what we don't like about our lved one, so much that we miss the opportunity to enjoy the things we do like. How do we know when we're being overly critical of our loved one? If you've been married for a length of time, you love your spouse, yet you find yourself always complaining to them about the little things they do that you don't like, is it possible your standards are too high? How do we learn to stop critcizing, overlook small faults and be content with the one we love?
