Why do I always think my girlfriend is cheating?

Insecurity is one initial thought. However sometimes if you have that feeling or hunch you could be right. Do habits change? Has she changed? Look for obvious changes.

If you have ever experienced trust issues with a friend/relative/ex-partner, it maybe hard to retrieve the same amount of trust from somebody else.

It could be a sign of communication issues. Open talk is key in a good relationship. You could also think if you have personal insecurities or self-esteem problems that could explain your doubt, and work on those.

Because one is afraid of losing that person. They are afraid they are not good enough. This fear creates a lack of trust in the relationship which will slowly drain the life from the relationship. One should develop trust in oneself and the relationship. It is the only way out of fear.

As A female, I see it that my guy feels this way when Im not showing the attention I should. Scheduling time for each other helped make sure he felt more secure.

If she is not cheating, then you are likely insecure. What makes you think she is cheating? Is it because you are comparing her to someone else or another relationship?

It might be helpful to consider when the thoughts of your girlfriend cheating started and what incidents make you feel that this could be true. Additionally, There may be some questions that you have not asked your girlfriend but might need to know the answer to in order to think differently. If you decide to discuss your thoughts with your girlfriend please be kind as it is also possible that your thoughts could just be thoughts.

From my experience, jealousy and these kind of emotions come from a personal insecurity. Maybe you've been cheated on before or maybe you struggle to trust people easily. Talk to your girlfriend about it, explain how you're feeling openly. You may even want to look into couple counseling if you both feel it will help!

Sometimes, when uncertainty strikes, it can make us doubt our partners and have these thoughts. Maybe a similar thing's happened before so you're more careful this time. And it's good to be cautious. However, having these thoughts can affect relationships in certain ways so it's better to talk it out with the significant other, so you both build a better understanding and it would be easier for both of you to deal with these uncertainties.

You might have some insecurities about yourself. Usually when we're suspicious or jealous it's about ourselves and not the other person.
