My boyfriend is mad at me for wearing his friends clothes

Phyllis

Hello darlings so I’m confused about something. I went out with my boyfriend to visit his friends and unfortunately I spilled beer on myself so his friend gave me his trousers but my boyfriend refused to talk to me when we returned home. After series of questions he finally told me I disrespected him by taking his friends clothes. Please did I do the wrong thing by taking the help from his friend? Is my boyfriend right about me disrespecting him ?
