Husband thinks I’m stucked up

So we had an argument and he said I’m stuck up, not the first time he’s said this. And honestly it hurts my feelings. I’m a serious introvert, I’ve been shy all my childhood and adolescent life. I’m not outgoing. I have anxiety doing any public speaking. I get awkward in conversations sometimes and don’t know what to say to keep them going so I avoid them. I’m the type to hide in my room if certain guest come over (sometimes I go and say hi, depending on who it is) The type of person to say something and then critique myself about what I should have said instead. But I don’t see myself as stuck up I’m a nice person and I don’t think I’m any higher than anyone. 😞
