Can’t get the thoughts of my head that I don’t want to stay in my relationship because I want to have sex with other people and have one night stands. Every time I see someone attractive, it triggers these thoughts. They’re really ruining my day and have persisted ever since I woke up this morning. I don’t know what is real anymore and what is OCD. Every time a thought comes into my head about living a Single life and having one night stands, I instantly think about my girlfriend to try and counteract the anxiety but it always makes it worse. I know it’s rumination but it’s so involuntary.
Recognize the thoughts as intrusive and maybe start by resisting your mental compulsions for 10 minutes then 20 and more each time :) also I'd recommend the book 'Overcoming Unwanted Intrusive Thoughts'
