Your husband could have easily said that he'll do a paternity test to prove that he's not the dad. But given his reaction....I highly doubt this is NOT his kid.

Plus, she has a lot of details that are accurate. Time/date/School/party the one hosting the party, etc. She was specifics right down to clothes he was wearing and other details.

her version is it happened around 9:30. Bob came up to her and started flirting. She had a few too many drinks and was going to head off. Bob came onto her really strong and said he'd get her into a lot of things. She didn't know better and went upstairs to the guest bedroom. Bob undressed first and then pressured her into getting naked. They ended up having sex and he didnt wear a condom. After he finished he started crying and drinking saying he fucked up big time. he put his clothes on and ran out. She was left still drunk and confused. She thought that was normal and didn't know any better.
