My (28F) husband (49M) lost his best friend (50M) from high school because he crossed a line with me and now I can’t stop feeling bad because I shouldn’t have said anything.

Two weeks ago my (28F) husband's (49M) friend (50M) had a horrible fight with his wife and she kicked him out of their house, so my husband and I decided to welcome him into our house. Well, he was living with us for a few days and at first everything was normal but then he started making me uncomfortable like never before. He started invading my personal space or brushing against me when he passed by, and things like that, and I refused to believe that he would do something like that after so many years of friendship, so I kept quiet and never said anything to him, but apparently that encouraged him more because he didn't stop.

One day I was in the kitchen and my husband was upstairs taking a shower and he said he wanted to help me but all he did was get behind me with the excuse of "taking something from the cupboard" to rub himself against me, and that made me feel very disgusted so that day I talked to my husband and fortunately he believed me and confronted him immediately and he flatly denied it and said that I was lying, that he should "put me in my place", and my husband hit him and it all ended in a horrible physical fight that could only be stopped by calling my BIL who lives a block from our house.

Since then my husband and him have not spoken again and I doubt they will because my husband is really mad at him, and I can't stop feeling bad, what if I imagined it all? I mean, we have a three month old and we haven't been sleeping much, and it is possible to have hallucinations when you do not rest well. They have been friends since they were in high school, it is his longest friendship and it was destroyed in seconds because of me, I should have confronted him alone to avoid this. My husband thinks that it's not like that, that the right thing to do was to tell him and that it's not my fault, but I feel that it is.

One of their friends that they have in common took his friend's side and stopped talking to my husband too, and the worst thing is that everyone blames me because they think that I brainwashed him and turned him into someone unrecognizable, and for some reason I let those words affect me, and I don't know how to stop thinking like that. My husband has supported me a lot but I still feel bad, is this a normal feeling? Will it go away with time?
