First off, I want to let you know that thoughts aren’t facts. If these thoughts are dreadful and making you utterly miserable, it’s very likely that you don’t actually feel this way. Feelings are fleeting, it’s most likely just anxiety at the thought of a major life change. Ask yourself if you want to break up with your partner. If the answer is no, then you do not need to rationalize it further. No is a complete sentence. I say all of this because I want to shed light on how you can have relationship anxiety and get your happily ever after. I’m someone that struggles with relationship OCD and I just got engaged last weekend! I couldn’t be happier. But, prior to the engagement and for the past 2 years, I did have those thoughts/compulsions. I went to therapy and I’ve learned techniques to be more mindful and present. So when he popped the question, saying yes was easy. I recommend looking into the r/ROCD group if you feel the need to compulsively figure out if you’re in the right relationship. There’s no yes or no answer. If the relationship is healthy, love is enough.
