I Need Your Opinion On This Issue That’s Threatening My Relationship

My fiance wanted to come to the house to see my mum but I told him I won’t be around because I’m about heading out to somewhere, so he asked me if my mum would be around, then I said yes and he said he would still go to see her and it doesn’t matter if I’m not around.

When I later got home that night, my mum complained that he came empty handed. He didn’t bring anything for her and she was the one who offered him her drink.

Although initially, I didn’t see anything wrong with that but when my mum expressed her displeasure, I later called him to ask why he came to the house empty handed then I let him know I wasn’t happy with him, that it would have been better if he didn’t come. He tried arguing with me but I hung up.

Since then, we haven’t spoken to each other nor visited each other. Was I wrong?
