My father-in-law is accusing me of horrible things. I'm shocked and traumatized, what should I do to cope?

It was at night and I did my daily routine before bed. When I was done, I went to my husband who was standing and watching a court hearing of a young boy being accused of raping a woman and was found not guilty due to lack of evidence. As I was waiting for my husband to say lets go to bed, I stand there beside him and watch. All of a sudden his dad just looked at me and started saying things about a movie, I can't remember the specifics as I was in total shock. He went on to say that, "I invited him to have sex with me the other day." I was trembling from the accusation, upset, panicking and really angry. In my entire life I have never been accused of such a thing from an old person whom I considered as family. My husband was defending me which went into arguing with him. He started bashing my beliefs because I am a born again Christian and I don't have a Church here in Australia yet. Before I came here, my husband already told him that I am not to be involved with family affairs and us couple going to Church as they know, we are figuring it out yet. He also accused me that I was perving on him when I accidentally open the toilet door and he was there doing his thing. It was morning when we got inside with my husband and I thought everyone was outside as I saw everyone in there, I will always knock the door it's just that time that I am pretty sure everyone was outside. I was with my husband when I open the door as we are heading to the kitchen to have breakfast, I told him I will go to the toilet first. We already settled and apologises each other but it was brought up again in a most awkward situation. He also accused me of flushing pads in the toilet when it won't flush as it is due for a pump already.He was too pushy of bringing me with them to their Church which I don't really like. He'll come to me always complain about other Churches and some people doing naughty stuffs in their life even on the serve in the Church. This keeps happening, I am always pinned down to listen to what he was talking as he'll keep saying, "Manilyn, you should listen to this, I don't care what you are doing, you should listen to this, now listen."As a well mannered obedient Filipino person, I don't have a choice but to respectfully listen unwillingly with my head starting to ache. During the days my husband will tell him things that I should not know, he'll just keep saying, "It's my property! I can say whatever I like!" By the way, we are on my husband's dad's property (farm) as my husband is voluntarily helping him to do some things that he can no longer do. In the end, he just complained about my husband not helping enough but he will always tell him off that he can't do things on his own and what he wanted to do as it is his property! By the way, I can only help to do things in the kitchen as my husband don't want me to do much to let people depend on us to do everything. My husband never wants to be paid or be rewarded by anything, he just wants to help fully but he will always criticised him instead.
I was already alarmed about the situation of the plastic buckets incident used for washing clothes which I accidentally break the handle. It got him into rage that traumatises me as well. He got to angry asking my husband with happen. My husband just keep saying he already knew with what happened. And he just keep staring at me like he's gonna bite saying to really say what happened and telling me I am not always right. Imagine being traumatised by just a bucket and how angry he is. Now help me, I can barely sleep thinking of things all the time. I keep remembering. it really hurts being accused. My husband decided to cut ties with him but, the wound is still bleeding.
