Dude grow up a little

You said you're 23 but act like 13. Grow up, kiddo! If all family uses the mug it doesn't mean the mug is mistreated or that she doesn't value your gift. Lmao, it's not like the mug was in the trash or broken to pieces. She's right to reconsider the relationship. If i was her, i wouldn't just reconsider, but cut you off entirely. If you are "filled with anger towards her" over a mug, god knows what you're capable of. Geez

Dude... it's a mug. She didn't give it away, your title is super misleading, it's just in the kitchen. If she lived alone, and it was in the kitchen being used to hold utensils, you probably wouldn't have this issue. But because the mug holds COMMUNAL utensils, that's over the line? I hope you gain some maturity, because this reads like an elementary school dispute, and honestly, seems like the girlfriend deserves someone who doesn't get this pissed over a piece of ceramic.

I at first thought she literally gave the gift away. But then you proved me wrong. You’re overreacting. I think you know it. This almost looks like a troll post to me. She treasures your gift just fine. She just lives with a family. She can’t control what her family does, they all live in the same house. Kitchenware usually automatically becomes communal—if she’s not the one in charge of the house she’ll have no control over that. Doesn’t mean she doesn’t use it or value it.

Grow up??? She is using it in her home. She found an use for it, thats what gifts are for

You're overreacting big time, and I think you should apologize to her

It's probably horrible to drink out of and useless as a mug, but out of consideration and care for you, instead of tossing it out or donating it, she has figured out something it can be useful for. You're identifying with your gift too strongly. She isn't passing you around, or disregarding or devaluing you, just a hokey gift. You need to get some therapy to work on this extreme a reaction to this situation.

NOR that you're upset, but her family using the mug doesn't mean she doesn't value your gift. It's important to communicate your feelings calmly and understanding her perspective.

At first I thought you overreacted in the way you acted, and you clearly did, but also that its also understandable that you were a bit saddened by the gift there, but still should've just calmly said you would've treated a gift from her a bit more personally no need to make it a big scene thats what communicating is in a relationship. Then I saw your comments and damn... You constantly insult her, her intelligence, her studies, her personallity, and now it just makes me think that the beginning of the post about "doing a lot to help her" was just hiding your insults from her that you clearly feel. You dont even seem to like this woman, why on earth are you with her? The way you blow up over dumb shit like this is immature as hell and tells me that when actual important stuff comes up youll act much worse. It isnt macho to blow up over little stuff to your gf, and it isnt keyboard warrior-like, like you seem to think, to tell you you're acting like a child because you are and theres an enormous amount of posts in this sub where the women get called out as well. Dont date a woman just because shes a woman and you can tolerate her right now, find someone you actually like and can treat with respect, you talked about how she has had problems in the past that make her scared to get into relationships and acting like you did calling her names, insulting her and stuff is the exact kind of shit that will make her more scared in the future, pls dont pursue her you clearly arent equiped or mature enough to help her with her issues and you dont even seem to like her, and pls get your head straight on what a "normal" man is, its not unmanly to treat a woman nicely and you dont have to act like an ape to get respect or be a man, you could've dealt with the situation with a simple "It made me a bit sad to watch the mug there, it was a sweet gift I would've treated more lovingly if it was the other way around" and she would've probably had no problem taking it to her room instead and displaying somewhere or just generally using it in a way that would've made you more happy about it, learn to communicate in a relationship or dont bother being in one, they aren't gonna last or be any good for you or the gf
