Need serious advice. My husband is accusing my dad of horrible things.

I'll start off by saying I had a really hard awful labor. I won't go into details but my family members that waited outside my room at the hospital thought that I had died while giving birth. They were all so relieved when they were finally allowed to come in and see me. I was completely exhausted and drained. My breasts were exposed but I was so overwhelmed and tired and emotional I didn't care or really even notice. Well my dad took a seat across the room from me and according to my husband he was "staring at my tits" before the nurses covered me up. I love my dad. I'm close with my dad. He's a wonderful father and a good person. My husband thinks he's a "sick fuck" and a pervert (quotes) and has gone as far to say that he's a pedophile and a rapist and that he should never be allowed around our daughter alone and that I shouldn't trust him and even said that I'm a shitty mom for not caring. I care. I feel awkward and weirded out that my dad looked at my breasts. But that does not mean I don't trust him or that I think he was looking at me in a sexual way, which is what my husband thinks. I don't know what to do. Any time I try to reason with my husband he accuses me of not believing him and making up excuses for my dad and tells me what a disgusting person I am for thinking it's ok. I'm so stressed and at a loss. I just so do not know how to handle this and it's killing me. I'm so sick of fighting with my husband about it and being called a bad mom because I don't think my dad will molest his granddaughter because he looked at my boobs. Any advice is helpful. Thanks.
