AITA for stopping my daughters wedding over the lack of a paternity test?

I’ll get straight to the point. My daughter, Pam, 24, got pregnant. She wasn’t dating anyone consistently at the time it would have happened, and she admitted to having hooked up with some guy she didn’t know that well. She later said she found out she was pregnant, and she was going to abort. She changed her mind and decided not to. <br><br>The father was someone she had casual sex with and claimed it was a one time thing. He had a girlfriend. 6 months later he contacted Pam again and broke up with his girlfriend and said he wanted to get back with Pam. He learned she was still pregnant. Pam, who was already emotional, accepted him back and within a year, they were engaged. He was the only boyfriend she had that I really didn’t care for. <br><br>Pam wanted to get married at the courthouse, but we insisted she not. We fully paid for her dream wedding. <br><br>Yesterday, the day before her wedding, her fiance told me he was glad the wedding was finally happening, and he was going to marry Pam no matter what because she was a prize. I told him I didn’t appreciate that and he repeated he was glad the wedding was finally going to happen, and he was going to marry her no matter what. The conversation ended with me telling him that if he wanted to back out he could, and that my daughter wasn’t some prize to be won. <br><br>Later that night at the rehearsal dinner, I announced the wedding was cancelled and my daughter was getting a paternity test. She flipped out and said the DNA test was irrelevant. I said it was 100% relevant because I wanted to know if I was paying a tremendous amount for her wedding to some manchild who was going to marry her because he thought he won some prize. <br><br>Her fiance got angry and tried to say I was acting crazy, and I told him that if he was so confident he was the father, why was he so scared of a paternity test? He said he fully believed he was the father, but he also says he fully planned on marrying Pam no matter what. He said he was livid that I was trying to change my daughters mind about marrying him and I said it wasn’t about that. I said if he’s the father, he should be grateful he is able to know with 100% certainty that he’s the father or at least have the option to know. He said he was too and was acting like his feelings were hurt that I had changed my mind about the wedding. <br><br>Now her mother and I aren’t the people who are paying for this wedding. We also fully expected her to call off the wedding for the paternity test and have been saving our money for the past year on top of what we spent. <br><br>Her fiance has gone on an anti-customer service crusade online and he’s telling lies and bogus stereotypes about people over 40. Many people have contacted us privately and told us his behavior in the video was very inappropriate and seemed entitled. <br><br>AITA?
