There's nothing wrong with missing your partner when they're away or wanting to spend time with them because you genuinely enjoy their company. But if spending time with your partner is a need and not a want, that's may not be love. It's a sign of attachment issues. "If someone is insecurely attached, they may be overcome with separation anxiety or subsequent anger if their partner is unavailable," Nicole Issa, PsyD, licensed psychologist and founder of PVD Psychological, tells Bustle. Basically, being away from your partner causes you emotional distress so you act out in ways that are toxic for a relationship. If this is the case, it may be best to speak to a therapist or loved one about why this may be.

Your attachment style, which is shaped by early experiences, is your pattern of relating to other people. It influences things like who you feel connected to, your expectations from people, and your ability to be independent in a relationship. If you're not wired for love, Dr. Issa says you may avoid getting close to others, pretend you have no needs or expectations, or dismiss your own feelings. If your parents never met your needs, you may have a hard time believing other people can, so you won't bother trying.

Imposter syndrome is a psychological phenomenon where a person feels like a fraud for their achievements or things they've earned. In the context of dating, someone with imposter syndrome may feel like they don't deserve their partner for whatever reason. "In practice, these self-titled 'imposters' may feel as if they’ve cheated people into thinking that they’re better than they actually are," Samantha Morrison, health and wellness expert for Glacier Wellness, tells Bustle. "Likewise, any good that may come their way is brushed off as undeserved, effectively preventing them from ever allowing themselves to be in a loving long-term relationship."

If you come from a dysfunctional family background, it may be harder for you to develop a fulfilling and healthy relationship because you don't know how to connect with others. As Irina Baechle, LCSW, relationship therapist and dating coach, tells Bustle, "Coming from an unhealthy family can make you an insecure, disconnected adult who feels like you're not wired for love. You may struggle to build and maintain intimate relationships, and often feel lonely or isolated." But you can change this dynamic, with the help of a therapist.

Due to dysfunction from chilhood, you may fear being "smothered" by someone else's needs. "This can happen when parents focus on their needs rather than those of the child," Karen R. Koenig, MEd, LCSW, tells Bustle. "In these cases, the child’s physical and emotional needs do not get met and they, therefore, equate emotional attachment with losing a sense of self." So as adults, they’d rather be alone than face the possibility of feeling smothered.

Consistency is important to stability. But if you grew up in a household where a parent went from one extreme to the next (overwhelming you with their needs and then rejecting you for not meeting their's), this can cause you to be wary of relationships. "You may not wish to become involved in close relationships because you would never know what to expect from someone," Koenig says.

If your parents are divorced or you witnessed them fighting a lot as a kid, this will affect you. "These kinds of experiences lead to the formation of beliefs about relationships and their probability of happiness and success," psychotherapist Toni Coleman, LCSW, CMC, tells Bustle. "If someone believes that relationships are likely to be unhappy, they'll avoid getting attached and being vulnerable." But in order to have a loving relationship, healthy attachment and vulnerability are key.

Just because you have a hard time being emotionally available, doesn't mean you can't find or keep love. Everyone's capable of love. But when you're not wired for it, you may need to put in the work to resolve deeply rooted issues from the past. Going to a therapist can help you with that. If you can work on being more emotionally available, you can have a healthy, loving, and long-lasting relationship.
