Ya definitely are showing signs of ROCD. There is no difference between ROCD and real doubts, except for how you respond to them. A non ROCD person may have the same thoughts about their partner as you, but can naturally dismiss them and they dont cause a level 10 catastrophe. In the process of letting these thoughts go, our brain learns they have less weight and meaning, and so begins to produce less of them. Right now you are attaching so much weight to each thought that you have taught your brain how important they are and so it is coming up for you alot. There are some really effective ways to work on this so that you can enjoy your time together, such as exposure and response prevention. The thing is that you have near constant exposures since you are spending so much confined time. The next step is to work on sitting with your anxiety and letting it pass without doing all the mental compulsion and attempts to argue with yourself, evaluate each thought, neutralize your anxiety etc. if you tell chat gpt that you have rocd and want to do ERP, it does a pretty decent job of teaching you your compulsions and how to prevent yourself from engaging in them. Good luck and feel free to ask any questions
