Just venting

I am in a relationship. I am engaged, I love my fiance we have been together almost 2 years ( in 2 months) and our wedding is this September (yay!) I know I have had weird thoughts about liking my friends even before I was in a relationship like wayyyy long ago. Ever since I have been with my fiance (this is the longest relationship I have ever had… and it’s my forever lol ♥️) sometimes when I have a coworker that’s a guy or a girl (but mostly guys) like everything will be super ok and fine and whatever then my brain with randomly be like “oop you like them” “you chose wrong” “you’re in the wrong relationship” “you like your coworker”???? Like recently i work with a guy that i used to think was cute like in 2022 from my first job but like we never dated and whatever, but we became like pretty good friends over the years of me leaving and coming back to the same job lol. This time around we have gotten to become pretty good friends and i want my fiance and some of my coworkers to meet and them to be friends because i feel like they would totally vibe. But now like recently my mind has been being like “oh you like him” “you wanna be with him” “you wish you dated” or like i will think about like oh what if we dated What would have happened just things like that. Or like “oh what if you just want to like be single and date other people”??? I love my fiance so much i would never want to hurt him I want to be with him forever and marry him and everything but sometimes when these things pop up in my brain I feel like I am cheating on him an I wanna tell him all the things in my brain but I try not to because I know seeking reassurance doesnt help. Idk has anyone else gone through this? (Ps if you read this whole hot mess youre an angel lol thanks for reading my vent🤍) super tired 🥱
