Why do I always think my girlfriend is cheating?

because you dont trust her, that's the only reason. you think like that. increase your bonding and make her more comfortable.

Question your beliefs, question your thoughts. Probably because it's either true, or your not confident in yourself.

Maybe this is some insecurity on your behalf. Do you maybe not trust her because you do not trust yourself? Have you been cheated on before?

Talking from personal experience, it sounds like you are insecure about yourself. Do you have a good relationship with yourself? Do you like who you are? If not, working on yourself might be necessary. If you're not insecure, it could be that you have had bad experiences with previous partners. Have you been cheated on? Lied to? Abused? Maybe you're in the mindset that your girlfriend is going to betray you because everyone else has. Has your girlfriend actually given you a reason to believe that she's cheating? If not, then it's important you work on your level of trust with her, otherwise you will drive yourself crazy thinking she's cheating.

You are confused. You think you aren't enough for her. I had that fear too, my boyfriend is too handsome. I thought I am really ugly and he can easily get anyone. But now I am proud of me. I think I am so pretty. I know he loves me truly. And he loves only me.

This has to do with trust, maybe you’ve had bad experiences in the past or maybe you are protective

Communication is the key to success. If you never express it in words, how are they supposed to know?

If your girlfriend shows signs of cheating, maybe you should confront her in a calm way and talk to her about it and maybe request that she is honest and open about her actaions so no one is emotionally hurt.

I had the same issue and always assumed my girlfriend was cheating! In a relationship - trust is a very important part of keeping a healthy and stable relationship! If you feel like your girlfriend might be cheating on you, consider speaking to her about how you feel!

What we think arises from our feelings and experiences - if we have been hurt or cheated on in the past then we feel like there's a chance of it happening again. Or alternatively if we have low self-esteem or feel our partner is better than us then we convince ourselves that they'd seek someone "better". But in both these cases it is important to recognise that these are all our OWN thoughts - not the thoughts of our partner, and the past does not predict the future. Your thoughts and feelings are valid, but that does not mean they are true.
