Separation anxiety in adults from partners is more common than you might think. 

So, what can you do about it? 

This article explores the symptoms of separation anxiety, its underlying causes, and practical ways to cope. Whether you’re struggling yourself or trying to support a partner who is, understanding this anxiety is the first step toward managing it effectively.

What is separation anxiety in relationships?

Separation anxiety isn’t just a childhood issue; it can deeply affect adults, especially in relationships. Imagine feeling a wave of panic or an intense worry every time you and your partner are apart. This is what separation anxiety from a partner feels like.

Research highlight = Recent evidence indicates that adults can suffer from moderate to severe separation anxiety. A research article on adult separation anxiety disorder (ASAD) suggests that those with ASAD may exhibit more pronounced symptoms of depression and stress, higher neuroticism scores, and increased levels of disability.

In relationships, this anxiety can show up in different ways: incessant texting or calling to check in, seeking constant reassurance, or even experiencing physical symptoms like a pounding heart or a knot in your stomach.

According to Jennifer Jacobsen Schulz, LCSW:

People with separation anxiety are often fearful that something harmful will happen to loved ones during separation, which can make being apart feel terrifying.

It’s more than just missing your partner; it’s a relentless fear that something might go wrong when you’re not together.

5 major separation anxiety symptoms in relationships

Separation anxiety from a partner can be a daunting task to face. It’s a real and challenging issue that can manifest in numerous ways, often creating hurdles in even the strongest relationships.  

Let’s understand the major symptoms and their types:

Emotional symptoms

1. Intense worry and fear: Constantly worrying about your partner’s well-being or fearing that something bad will happen when you’re apart is a hallmark of separation anxiety from partner.
2. Overwhelming sadness: Feeling excessively sad or even experiencing episodes of crying when your partner is not around.

Physical symptoms

3. Physical discomfort: Separation anxiety from a spouse can cause physical reactions such as stomachaches, headaches, or a racing heart when separated.

Dr. Jenni Schulz highlights that:

Physical or somatic symptoms of anxiety are common, and they occur when intense emotions manifest as aches, pains, or discomfort within the body.

Behavioral symptoms

4. Clinginess and overcommunication: The need to constantly call or text your partner, seeking reassurance, can be a significant behavioral sign of separation anxiety from partner. This can sometimes lead to tension and misunderstandings.

Cognitive symptoms

5. Intrusive thoughts: Experiencing persistent, unwanted thoughts about something terrible happening to your partner or your relationship can be exhausting and mentally draining.

What causes separation anxiety in couples?

Separation anxiety in couples is a multifaceted issue with various underlying causes. Let’s walk through some of the main reasons why this happens.

1. Attachment styles

One of the primary reasons for separation anxiety from a partner is rooted in our attachment styles, which develop early in life. Individuals with an anxious attachment style often fear abandonment and have a deep need for closeness and reassurance. 

When they’re apart from their partner, this fear can trigger separation anxiety. This manifests as a constant need to check in, worry about the relationship’s stability, and feel an overwhelming sense of dread when not together.

2. Past trauma

Experiences of past trauma, such as previous relationships where trust was broken, can significantly contribute to separation anxiety from a partner. 

If someone has been betrayed or abandoned before, they may carry those fears into their current relationship. This past trauma can cause them to anticipate the worst when their partner is not around, leading to intense feelings of anxiety and insecurity.

3. Lack of trust and communication

Another key factor is the lack of trust and poor communication within the relationship. 

When couples don’t communicate effectively or when trust issues exist, it can exacerbate feelings of separation anxiety from a spouse. Misunderstandings, doubts, and unresolved conflicts can lead to increased anxiety when apart, as one or both partners might worry about the other’s actions or fidelity.

Empower yourself and your partner to build a foundation of trust and understanding that can withstand any distance.
