As master life coaches, we have found that human behavior is driven by what we value and what we fear; but unfortunately most of it is driven by fear. Even many of the nice things we do aren't driven by love, but by the need to earn validation — to quiet the fear of not being good enough.

Here is a list of common fears and how they may impact your relationships. Take your time and think about how each might be showing up in your life.

1. Do you fear failure (not being good enough)?

This fear is the root of low self-esteem, and we all have some of this, to some degree, every day. Low self-esteem is the main cause of relationship problems, because the insecurity it produces makes you needy for validation. That need for validation means you have an empty bucket and you expect your partner to fill it. You might even make your partner responsible for how you feel about yourself. This is a recipe for disaster, because he or she can't give you enough validation to fill your bucket when you are emptying it with negative thinking about yourself at the same time.

If this is a big issue for you, you are probably getting angry with your partner on occasion for not giving you what you need. This creates a rocky love life filled with disappointment and frustration.

2. Do you fear being rejected, left or abandoned?

You may fear this if you have experienced some loss in your past. Even if you lost someone to death, and it wasn't their fault, you may still subconsciously fear abandonment.

This fear can make you controlling, possessive and suspicious. You probably ask a lot of fear-based questions about what your partner is doing or where they are going. This shows a lack of trust (and is at some level an insult to your partner's character). If this goes on for a long time, you might create what you fear, because this behavior can push your partner away.

This fear of abandonment creates a relationship where fear is even driving your loving behavior, making it more clingy.

3. Do you fear not being perfect?

If you have perfectionism fear, you believe your value is tied to performance — meaning the way your house looks, the way your family behaves, the way you do everything in your life determines your value as a person.

With this belief driving your behavior, there is a lot of unnecessary stress and pressure behind everything you do. It also means that your need to feel good enough will come before everything else. You might even treat the people in your life like employees who work for you and are expected to follow your rules all the time. This can make you controlling and domineering at times.

This obviously damages relationships because people feel you care more about things, appearances and performance than you do about them. You can have everything perfect, exactly the way you want it, or you can have rich, connected relationships; but you can't have both. Eventually the people in your life will give up trying to meet your expectations and want out.

4. Do you fear not being loved or approved of by others?

This means you base your self-worth on what other people think of you. This can drive all kinds of bad behavior, depending on who you are trying to earn approval from.

If you are trying to earn validation from your spouse, you may become overly focused on managing their emotional state and feelings toward you. This could mean often betraying yourself, and constantly worrying about trying to be someone you're not.

If you are trying to earn approval from people outside your home, you may spend all your time and energy there and neglect your family. This can create resentment and damage the connection with those you love.

5. Do you fear not having control?

Being a "control freak" is all about fear. You subconsciously can't feel safe or peaceful unless everything is going the way you think it should. This can be poison in a relationship, because your need for control will trump your need for connection.

You will often mistreat the people in your life, especially if they aren't doing things the way you want them done. People will, again, feel you care more about things than you care about them. You might also be pushy or have anger issues when things aren't "right." If this shows up in your relationship, your love life is probably often in conflict and disconnected.

6. Do you fear being taken advantage of?

Our clients with this fear tend to be controlling and constantly on the lookout for anything that could be seen as mistreatment or disrespect. They often see mistreatment in everything, even when it isn't there. If this fear is present in your life, you are probably offended, angry or defensive much of the time. This can create a toxic relationship if you are constantly disappointed in or angry with your partner, who will feel insulted or attacked often.

If you want your love life to thrive, and for you and your partner to feel happy and safe, you must learn how to live from love, not fear. You must make sure your choices are love-motivated, and you are focused on making your partner feel safe, loved, admired, respected and wanted.

Remember that it is OK to seek professional help to confront subconscious fears that can wreak havoc in your love life. The right help can set you on the path to a happier, more love-filled life.
