When you get married, you are psyched for so many reasons. You are finally with your one-and-only, forever. You've got a partner in crime. It's you and your spouse against the world. You've got each other's backs, you're best friends. Shall we go on? Oh, yeah. One more. You'll never be lonely.

Uh, not so fast on that last one. Research shows marriage can be one of the largest sources of social stress. When expectations are not met within the union, it can lead to depression, resentment and, yes, loneliness.

How Marriages Become Lonely

Researchers found that one or both members of a couple can feel isolated even if they spend a lot of time together. But why?

"Sometimes marriages fall into an autopilot pattern," explains Wendy Walsh, Ph.D., relationship expert and author of The 30-Day Love Detox. "Partners no longer court each other or exchange the care that they did in the early days and they become more concerned with selfish interests."

Other times, one partner in the marriage may be unhappy but unable to communicate that effectively, which can lead to feelings of loneliness too, she said. Spouses who are also parents face an even greater risk of feelings of isolation or abandonment, especially when one parent is playing a role (worker or caregiver) that makes him or her unhappy.

Fix the Feelings of Isolation

"When children arrive, sometimes couples fall into traditional gender roles or battle about gender roles for the first time," says Dr. Walsh. "One may feel a need to work more outside the home to provide for the family, another may feel a need to nurture more. This is definitely a time when the battle lines can be drawn. Children put a lot of stress onto a marriage."

1. Find the source.

For whatever reason you're experiencing loneliness in your marriage, Dr. Walsh offers these three tips to help you start repairing your relationship.

Instead of automatically blaming the marriage, or bottling up any negative feelings, take some time to figure out why you feel the way you do. Perhaps the real reason for the feelings of isolation stem from something internal that needs to be addressed.

2. Avoid blaming your partner (or yourself).

Ask yourself whether it's about something that's actually happening in the marriage, recommends Dr. Walsh. "Are you being abandoned or are you perceiving that you're being abandoned?"

Wallowing in your own sadness or allowing it to morph into anger won't solve anything -- and it could actually make you feel worse. If your spouse is acting in a way that bothers you, confront him or her with a positive tone and try to express that. Blaming a spouse for working too much, or not paying enough attention to you, or doing anything else that you perceive as "wrong" will only cause him or her to be walled off from you. Approach issues in a constructive, open way.

3. Don't rely on your spouse for everything -- spread your wings.

"It's never anyone's fault," says Dr. Walsh. "It's better to ask someone to help you process your feelings than to blame them for your feelings."

If you expect your spouse to fill all the roles of best friend, emotional confident, lover, domestic partner, co-parent and your primary intellectual stimulant, you might always feel a little disappointed. Instead of relying on your spouse to fulfill all these needs to the fullest, divide those tasks among a few platonic friends. "This is a way to take some of the pressure off of the marriage and improve self-confidence too," says Dr. Walsh.
