It is okay; I've been there! I know it's hard. But remember that love ISN'T only a "sparkly feeling". Is a commitment, and a CHOICE. What helped me is understanding more about rocd (than I was able to recognise my rocd toughts, and treat them the way that they should be!!), do erp, therapy, and a lot of patience. You should EMBRACE UNCERTAINTY (maby I love him; maby not) and DON'T try to answer to your thoughts. (There will never be an and if you answer: than you have to prove yourself that your answer is true-> more questions!) Also, a hard pill to swallow is letting go a lot of BAD BAD BAD beliefs that family, friends &society told me. - It is okay to not feel the sparkle every time. It is okay to feel apathy or indifferent about your partner sometimes. It is okay to don't be SUPER EXITED if he kiss you etc. All that doesn't means that you don't love him. - there is not THE ONE. The right one, doesn't exist. -emotions reflect thoughts. If you change your thoughts, your emotions will follow. - have doubts, ISN'T an answer.
But remember! Feelings can and will come back! Things will be better, I'd you start and keep doing constantly your healing journey!
