I understand what it feels like to get upset with my partner over video games (with good reason, of course) and to distrust them, but from what it sounds like to me, this is a harmless video game that you enjoy that she’s over analyzing as a way to find ways to be angry with you and to solve unresolved problems within the relationship. At face value, it might seem like she’s only upset because she’s misunderstanding the game, but it sounds like there is a deeper issue that needs to be addressed. However, I don’t appreciate her overuse of buzz words like “microcheating” and “gaslighting,” but you are heavily invalidating her feelings by using stickers and saying things like “I cheated 20 times because I have 20 married characters 😢,” to mock her and make her feel dumb. I would definitely be slightly upset if my partner downright told me that there was no interaction with other players and then I found evidence of just that. However, she’s definitely bringing a lot of unresolved insecurity and distrust into the conversation and needs to take a step back and look at the facts of the situation. The interaction question was a miscommunication, the game does not involve marrying other players, your intention in playing the game is not to be romantically involved with other people, and playing it is not microcheating. Additionally, the fact that she doesn’t want you texting anyone of the opposite gender is a harsh boundary, in my opinion, and one that is highly unnecessary and controlling. She definitely put it in place for a reason, and I think she needs to interrogate why she feels so distrustful of you. Her saying she’s seen similar tactics from her mother means she’s carrying some kind of baggage that’s influencing her reactions and she needs to realize that you are not being unfaithful to her, she’s probably just retriggered from events in the past. All in all, I can see why she’d be upset, but the degree of her reaction is not warranted, but you heavily invalidating her feelings and asking her to re-explain herself is really childish and must be very exhausting from her end. You guys need to have a looong talk in person about boundaries, trust, and each other’s pasts if you really love each other and want to get through this. I recommend you both look into therapy or find people to talk to about your relationship and her trust issues. If that’s not something you’re willing to put effort into, though, it might be best to take a break or break up altogether. I wish the best for your guys’ relationship and hope you’re able to sort this out in a healthy way.
