If your relationship is stagnant, it's time for an open dialogue—here are some conversation starters.

A long-term relationship can experience a lull in various forms. One way it may manifest is through a lack of engagement during meals, while another could be sleeping apart for extended periods.

It's unlikely that two people can remain in a relationship for an extended period without experiencing some level of disinterest or disappointment.

Despite appearances, a couple may be dealing with hidden or unclear difficulties even when their relationship seems healthy.

In 2022, while promoting her book "The Light We Carry," Michelle Obama shared her struggles in her marriage.

According to an NPR's Life Kit episode, long-term relationships often experience periods where one or both partners are unhappy with the partnership's functioning.

"Obama stated that being prepared for prolonged discomfort is necessary, with "long" meaning it can last for an extended period of time, possibly even years."

If you're going through periods of unease or apathy, it can be challenging to rekindle your relationship.

Renowned psychotherapist Esther Perel advises that the first step to reigniting a romantic flame is to have an honest conversation. She recently released "Esther Perel's Desire Bundle," a duo of online courses that teach you how to reignite a romantic flame.

"Take the initiative to revive your relationship," she advises CNBC Make It. "Don't simply blame your partner and wait for things to die down. Instead, express your desire to rejuvenate the relationship."

1. Address the obvious

"We haven't discussed our relationship in a while. I've been reflecting on how well we manage our household, social life, and family responsibilities, including taking care of our children. However, I often feel that our relationship is not given the same attention."

2. Express what you feel is missing

"We don't often ask each other, 'How are you?' or hold hands anymore, or simply look in each other's eyes and smile and say, 'We did well.' I miss you."

3. Ask if they're open to making a change

"Would you like to reconnect with me and prioritize our relationship over work?"

'Even the cactus can die'

If your partner is interested in trying, the next step is to schedule some activities that spark curiosity and excitement in both of you, according to Perel.

Instead of going to the gym, try a yoga class.

"Perel argues that people are not ignorant about what to do in relationships; they have experience with it. However, they have stopped doing it and have treated their relationships like a cactus, which eventually dies, leaving them surprised."

Resuscitating a relationship is not just about having sex, according to Perel.

"She emphasizes the importance of rekindling the energy and vitality in relationships, stating that sex alone may not be enough to achieve this."
