Question:  For love to last, what are the negative habits to change as soon as possible?

Answer:  You’ve probably met couples in which one or both partners interrupt the other person in public.  You might even be that couple!  Sevda and Tarik were friends of Gail’s (my wife of 30 years) and mine during our early years of marriage.  At parties or social gatherings, Sevda, a university professor, insisted that Tarik, a physician, was an “interruptor.” She also insisted that she was expressly not an interruptor. And she confessed that Tarik’s tendency to interrupt created significant marital difficulties.
She was right—it did, and Tarik was oblivious to the damage.  Men are often unable to see the effects of their actions during interactions and conflicts. Male heart rates do not rise as high as women’s during a marital conflict or stressful situation, and males may not notice as much about the impending issues because they are not as stressed by a situation.
Scientists Janice Kiecolt-Glaser and Ron Glaser have found that not only women’s heart rates but their stress hormones epinephrine and nor-epinephrine rise during stressful situations in marriage more than men’s.  Men’s “hearts,” literally, remain oblivious at times to the possible damage in their actions.
But that’s not the whole story.  Women often tend to mirror the public male behavior (interrupting, in this case) in private in more damaging passive-aggressive ways than they realize.  The very thing that drove Sevda crazy about Tarik in public also drove Tarik crazy about Sevda in private.
Interrupting more than one should is an example of a bad habit in marriage.  Bad habits, taken cumulatively, can harm or destroy love and marriage.  Fortunately, no marriage needs to be burdened by bad habits.  Here are five habits you can identify and work on right now.  If you are involved in three or more of these to a significant degree, your relationship could be in serious trouble right now or down the line.
To try to get immediately to the heart of the matter, reflect on this list separately with some blank paper on hand for writing notes, then compare your notes together afterward.  Do this list twice—once for yourself (i.e. “look in the mirror at yourself”) and then for your partner:  gently assess your partner’s habits.
Check List of Five Negative Marital Habits
Do you:
1. Interrupt your partner in public or private? Perhaps you interrupt your partner in both settings. If so, give some examples of both. If just one setting, give some examples of dialogue of interruption in one setting. Some interruption is normal between best friends, but do you do it too much?
2. Avoid doing things you know make your partner happy?  Perhaps you know that your partner would be very happy if you cleaned the house, but you avoid doing it. Perhaps you don’t just avoid doing it some of the time (some of the time would be a compromise), but instead, you avoid doing it all the time. Or you do it only when your partner forces you—perhaps through bribery, begging, or anger.
3. Avoid doing things sexually that either you really want to do and/or that you know your partner needs and wants to do? Give examples of sexual experiments you or your partner
want to try—write down why you avoid them. Be specific. If you remember conversations you and your partner have had about these things, write at least one of those conversations down.
4. Criticize your partner too much in public and/or in private? Some amount of critique, judgment, moralizing, and correcting of a partner’s behavior is normal in any long partnership. You care about your partner and figure you know what’s best for him or her. But do you criticize, judge, become reactive, or correct your partner on more than just a few things? If so, list those things.
5. Let your partner criticize, judge, moralize about, and correct you more than is safe for the development, growth, or stability of your own identity and self? It’s normal for all of us to defer to our partner’s critiques sometimes—if we didn’t, we’d lack an essential humility in our relationship. But if you are getting critiqued every day, and if you constantly assume your partner is right and you are wrong, your self-confidence is probably being significantly debilitated. List the critiques you “take” from your partner.
Assuming for a moment that you’ve both done this exercise, compare notes, talk, then use your lists and anecdotes as grist for relational improvement.  As needed, talk with a counselor alone or together about these lists.  If, as you talk about these things with your partner, one or both of you become either blaming or defensive, set a timer so that neither of you goes on and on (which can make the other defensive or bored or blaming). I suggest three minutes for each description or example of each bad habit (without interruption!). If either of you takes more than the allotted time or interrupts start the particular point over.  If one of you tells the story by blaming, start it over. If one of you becomes defensive, start it over.
As you talk about these bad habits in a timed or other safe way, and as you gradually (or immediately) do it without blaming one another or becoming significantly defensive, you will be practicing intimate separateness. This paradox is the key to healthy marriage—the ability in relationship and marriage to stand apart independently while still embracing one another lovingly.  Removing your bad habits can ensure healthy intimate separateness in your marriage—at the same time, just working on identifying and talking about those bad habits can be a first major step in the journey.
