Couples therapists agree that these behaviors may signal your marriage is on the rocks.

Even the healthiest long-term relationships have their fair share of ups and downs.

We asked couples therapists to share some of the not-so-obvious signs a marriage may be heading toward divorce.

Heres what to look out for, according to our experts:

1.

Youve stopped fighting with each other.

West Los Angeles clinical psychologistDavid Narangsaid he has observed this while working with male patients in heterosexual marriages.

At first, their wives may express their sadness and anger when they feel deprived of emotional connection.

This generates conflict and gets the husbands attention.

But when the wives stop sharing their frustrations, the husbands are often relieved.

Your lives have become more and more separate.

This increasing separation often points to a deeper disconnect and a diminished desire to share experiences together.

Youre not transparent with one another.

This will certainly erode the emotional connection between you.

You rarely talk about the future.

You confide more in other people more than you do in your spouse.

If someone else knows more about you than your spouse, this is a bad sign for the marriage.

Thats why its so important to speak up when youre struggling rather than bottling it up.

There is so much to know about having a great marriage, Whetstone said.

People cant expect you to wing it; you have to be mindful and deliberate.

Its so worth it.This article originally appeared inHuffPost.
