ok i love my boyfriend we've been together as in live in for two and half years. We were both given a set of keys for the apt and mail box. Some how his mail box key got lost like as we moved in to this place. I've had my keys the whole time. Well today he takes my mail box key off my keys and puts it on his. I didn't flip out but i said calmly asking what he was doing and why didn't he ask. He explains he needs to check the mail, i told him just borrow my keys then like the whole don't take the key off. He doesn't and says that he didn't want to borrow my keys he wants his but needs to check the mail. We take a shower to which it's still a conversation cuz he just basically doesn't get that i'm upset. i tell him he's not respecting my emotions. He goes on about i'm over reacting about the apartment mail key like as if it's not mine. I'm even more upset cuz i hear a tone in his voice like i'm being silly. He was washing his hair and said i didn't know you were so attached to a key. I left the room cause i was so mad. He after getting dressed he puts the key back on my ring i tell him i'll just put the key on the pool key ring since we only have one mail box key. We both apologized and i told him later he sounded like a jack *** about the attachment, he said he wasn't sure if i was messing with him till i left mad. We usually don't have this sort of arguments, usually barely have arguments to where i feel i need to leave due to me being upset. We are fine now but just asking. I feel as if it's my key i didn't lose mine and if it keeps getting swapped between key rings it will get lost, That's why i said to put it with the pool key That's alone and on a nob in the apt. I think maybe a little but he didn't ask i know we say what's mine is yours and what's your is mine but idk. Idk i don't get upset when he uses my phone or gets in my bag to get cig pack. Idk just my keys and my wallet i'm protective with idk why. Is this silly? Again we are fine we hugged and said sorry and all. Idk my feeling felt disreguard though
