Hi ! Can someone explain to me what is exactly false memories ? I think my OCD evolves. Thanks ! And happy valentines day !

i’ve been dealing with this “thing” since i was 15. (i’m 23 now) if i have a bad memory that i have done when i was really young or just an intrusive thought i feel like i need to tell my mom or boyfriend. it’s been on and off ever since but since January hit it’s been an everyday thing about the littlest things. mostly about my relationship. an example is i was talking to someone random at my job and we were talking about taxes and when im in deep thought or just thinking i do a thing where i bite my lip (not in the sexual way) and i had a thought when it happened “was that sexual?” and i felt like i did something wrong and i went for a while thinking that until i told my boyfriend about it. or like my ex’s face has popped up in my head in the most inappropriate times and i feel the need that i have to tell him. (my ex was not a good person) i feel like im a prisoner in my head everyday, trying to justify thoughts or remind myself that its just a thought. i didnt know that this was or could be a form of ocd. it runs in my family but i’ve just never considered it being this. i always called it anxiety or depression but i always felt like it is more than that.

Currently I have several different OCD fears that pop up throughout the week depending on the situation. I've noticed a commonality between all of them are the fears relating to memory/false memory. Today is the ROCD struggle I've been dealing with. I know OCD has been trying this on me lately because of how much I love my spouse. They are my absolute best friend and she's my world. I value our marriage and friendship more than anything. OCD has latched onto one specific female coworker. And I don't even know why because even if I were single I wouldn't be into her. Even still, OCD makes me think I've cheated on my wife every time I'm alone with this coworker at work. Always starts as a what if, followed by imagery, followed by feelings that I must've actually done something and can't remember it. Usually fearing I've kissed her. It hurts because I know I'd never do that to my wife and I love her so much...the idea of losing her kills me, especially if it were the result of something I did. Just wanted to vent. Feel free to share your experiences or vents as well

So, yesterday while I was laying in bed, I was relaxing when suddenly I had an intrusive thought about someone, but the thing is that it brought me a sense of enjoyment or calmness for a few seconds before it went away. Once it did, it was only until hours later when I realized what had happened and I began to freak out because I'm reading everywhere that when someone experiences this type of thing, the anxiety happens shortly after the enjoyment or "false" enjoyment. Can OCD do this?
