I need help getting rid of certain thoughts. I have a girlfriend, up until now the most beautiful woman I've ever been with. She treats me good, cooks and buys food for me. I do the same for her. Fuck regularly, etc etc. Regardless I cannot seem to shake thoughts of her doing things that would hurt me.

Thoughts of her fucking someone else, texting other guys ready to move on, that she's not as into me like she says (Even though her actions say otherwise)

I've read the sidebar many times, my question is not what to do to stay ahead of bad possibilities, it's how do I stop the thoughts that are debilitating at times. It wouldn't matter if it was another girl entirely, I would still have them. How can I stop them, please.
