MIL is irritating

How do I or do I even bother... telling my husband that his mom irritates me from the sound of her voice to her laugh irks me severely! Like I don’t say anything but my facial expressions says a lot. With our newborn it’s even worse and she lives in the same household which is even more irritating and when she tells people to come over to “my house” it’s even more irritating because she makes it known it’s her house her and her son bought. It’s like I’m jealous she has a home to call her house and I don’t? Like every woman wants to be the WOMAN of their home nor share it with someone else that is irritating. But I just don’t know how to kindly say these things to my husband without him snapping because that is his mom.
