Has anyone read Relationship OCD by Sheva Rajaee?
For the longest time i've been working through what I am realizing may be OCD arising from questions about my significant other and whether they are "The One." I frequent this subreddit, and the many comments of how users found "the one" that they had no doubt about, ever. For so long i've compared my feelings to my significant other to that standard. And that caused a whole host of issues for me.
This book has been eye opening so far, and very helpful for me. I highly recommend it to anyone dealing with intrusive thoughts about their relationship and whether they are with the right person.
