Is it wrong to hate my in-laws and avoid them due to past hurt?

Assalaamualaikum Mufti Saheb, years ago I did a mistake which seemed to be so great in my wife’s eye. She down graded me to the core and at the same time her brother and sister joined hands too in smearing me. The smearing was too much and so great for me to apprehend until I was very much ashamed and angry of what was done to me. My dignity and intergrity was smashed by both of them. As a result, my heart broke and I decided not to talk to my brother and sister in-laws. I could not even see them or hear their names as my anger gets boil up and I would try to avoid to communicate with them at all time. It has come to an extend that if ever they would come and visit my house definitely I would chase them away. But I do not stop my children and wife to see them although I do not like it for them to do so. In short I hate them so much and I consider without them my life is better. Please advise me as I do consider my act as severing the siratturrahim and what shall I do. It is extremely difficult for me as I fear Allah and His messenger’s words in regards to severing sirraturrahim. Thank you. Wassalaamualaikum warahmatullah.
