am I wrong

So my husband cousin and I have always had problems and we finally started to get along really well when her husband all of a sudden put his hand on the small of my back the. Pulled my hair and after that and later that day he put his hand a little lower so I stopped going around for a few days because I felt uncomfortable I also told my husband and he got upset then today I had to go over because her and I had plans and he grabbed my butt and when I went to leave he once again grabbed my butt I told my husband because he deserved to know  and finally was so overwhelmed I spoke to my mother Inlaw who happens to be my pastor she then pulled me and my husbands cousins husband aside and he denyed the whole situation said it was a complete accident and misunderstanding and now his wife is really pissed at me and I can tell I'm just wondering if I did the right thing by opening my mouth I was uncomfortable and wanted to make things end before they escalated am I wrong
