Would it be bad if I ended things with this man?

So I was talking to a guy for about a month until we went out on a date because i wasn’t in the area. He kind of invited himself into my house, stayed the entire day because he said he didn’t have to leave until a certain time (I tried dropping hints to kick him out, but obviously that did not work), told his entire family about me and then proceeded to call his mother in front of me and have us speak to each other. I also don’t feel any physical attraction. I’m wondering if it’s valid to just dump him
