Alcohol making OCD worse

I’m having the need to confess that I was unfaithful to my girlfriend (even though I was not) because I drank too much Saturday night and don’t remember every single second from my evening. My OCD immediately goes to that I cheated on my girlfriend and I need to confess my sins. I know it’s only OCD, but the thoughts are extremely strong. Any suggestions? Thank you, community.

Sometimes I had some relationship OCD and then I didn’t qualify for contamination OCD however I know in relationships partners like to be close and drink out of each others cup. My partner was thirsty and getting very hot and he asked for my drink and I gave it to him he felt better and I am so beyound happy he did! I feel a lot of shame admitting this, he told me I could have my drink back and I said thank you! 😊 He noticed I didn’t drink it because in my mind it says it is contaminated and I felt extremely bad that he noticed so I got a piece of gum to distracte us I then had to spit out the gum because it wasn’t a good flavor then my brain told me well… ( Ms.OCD) said if I don’t drink it it will hurt his feelings and then that means I don’t like him and then I drink it then I spiraled from there lol 😂 I am so sorry it wasn’t a weird funny story I was wondering if anyone else can relate? I was wondering if there is any advice I can please have? Thank you so much!! Please write down something in the comments if you are struggling because I want to help you all as well!! Thank you!!

I feel like the worst kind of person and I am ruining my husband. I don’t know how I’m going to be able to change.
