Relationship doubts

My relationship OCD has been severe lately and with seemingly no trigger to cause this flare up. I am constantly anxious, doubtful and panicked that I don't love my partner, overanalyzing whether or not I'm attracted to him, and ruminating on the numbness I feel when we are together. Every idea I can come up with to test and check to see if there's that love feeling, that attraction or interest/excitement in doing things together feels invalid, like it won't work. I get triggered further when my partner asks me if I'm okay, and that wave of panic comes back. I can't tell if this is OCD, or if it's my gut telling me it's not a relationship I should stay in. We've been together for five years, I'm not in OCD therapy, and I've been off meds for four months now.

I’ve been with my boyfriend for 3 years and he is an absolute angel. All throughout the relationship I would have nightmares and intrusive thoughts “what if he leaves/cheats”. And he would reassure me and treat me like the world revolves around me. Lately I’m realizing this was actually ocd and not anxiety as I had previously thought. I would get paranoid if he didn’t check his messages for a couple hours, I’d get anxious if I saw an ambulance heading toward his street while I was driving, I would ask for reassurance that he loved me constantly. Bear in mind, I have no reason to have these fears. My boyfriend is my best friend and has supported me through thick and thin and he’s amazing. One time a couple months ago I was being a bit snappy with him one night and I had the thought “only people who don’t like their partners are snappy with them” and it just stuck. Now I struggle with intrusive thoughts about my own feelings, do I love him, do I miss him enough, is my relationship going to end because this couple on social media broke up. I could deal with the thoughts about his feelings because he is so so good about making me feel loved but now I’m stuck in this constant guilt loop where I question my relationship for no reason then get anxious and feel guilty for even thinking that way because I think I’m manifesting it. Was wondering if anybody else in a healthy long term relationship has had this happen to them and how you talk yourself down :(

Over a year together with him, and I’ve just recently learned that I have relationship OCD and perfectionist OCD. We talked about it, but I can sense it breaking his heart when I tell him that I cycle between wanting to marry him to breaking up over and over everyday. Constantly evaluating every word or action of his, what shirt he wears that day, how he brushed his hair, what he ate for lunch, who he talked to, what he spent money on, etc any of these things can trigger me into an episode of intrusive thoughts about him not being the one, he’s wrong for me, I’m trapped, I need to get out. It can also swing the other way to me feeling an impulse to go to the courthouse and get married right there. I know that I love him, I always desire to spend time with him; and I picture my future with him in it. He’s such a wonderful person. I don’t know how to stop this emotional rollercoaster my mind straps me into everyday. I just want to be in love and feel secure. How will I ever get married with all of these doubts attacking me everyday?? I can’t stop myself from constantly lecturing him on his flaws and what he needs to change for me to love him more consistently. I feel like a cold and evil person. Will I ever have clarity? Is he really as flawed as I think he is or am I sabotaging the best thing in my life?
