Not going to one's sister in-law's house due to abuse

I am a married woman and I am having problems with my sister in-law. She is very sharp tongued and never misses an opportunity to say rude things to me. I am not a person who can fight back at her as this is not in my nature because of this I suffer emotionally and mentally for a long time due to the things she says to me. Will I be sinful if I stop going to her house as she always seems to have a problem with me? I will not prevent my husband from going.
