Am I being too sensitive ?

I’m not sure if I’m overreacting or if this is something I should take more seriously.

A little background: I grew up in a household where my dad never cursed or raised his voice. Disagreements were calm, respectful, and never crossed any lines. So now, when arguments get intense or involve swearing, it really throws me off emotionally.

About a year ago, my boyfriend bought a $50k pre-owned truck. I was hesitant about it at the time and gently warned him to be cautious. Since then, it's been problem after problem — back and forth to mechanics, issues with the dealership, and recently, he had cosmetic work done that left the truck with major damages.

He’s now trying to sell or trade it in. CarMax offered him $30k, and during the conversation, I said, “Oh, that’s not bad,” meaning I thought it was decent considering everything that’s happened. He immediately got upset and said, “What do you mean not bad? I paid $50k!” I calmly responded, “Well, no one’s going to offer $50k…cars lose value, especially with all the issues it’s had.”

His response? “F*** your comments.”

I was shocked and hurt. I told him, “You know what? Have a good night,” and hung up. This isn’t the first time he’s gotten aggravated like this over something small. It’s really starting to bother me.

Am I being petty or too sensitive for being upset by this? Or is this a red flag I shouldn't ignore. He didn’t directly tell me fuck you… but idk
