UPDATE - I 32F feel utterly betrayed by what I found out about my husband 34M

I posted about 10 hours ago, I was feeling so confused and hurt. I wasn't expecting so many responses, but I appreciate it.<br><br>I got home from work, walked in and told him I need to talk to him. He just said I know, I can tell you anything, we've had an open relationship our entire lives. I showed him my phone and started crying. He looked guilty as sin. He told me it was all some sort of "joke." He said that he and the rest of the boys at work made a bet that whoever got the most followers in a certain time frame would win $100. He said that he never intended on making it to that many followers and never expected for any of it to happen. He said that he was going to delete his account last night but the time got away from him. He also said that all of the messages were just jokes in the hopes of getting them to follow him so he could win the money. He claimed he never actually intended on meeting up with any of them.<br><br>I told him I don't believe him, and I told him I want a divorce. He cried and begged me to give him another chance. He promised that he'd do anything. But all I can think of is how could he do this to me? How could he even think of doing this? Everytime he tried to hug or kiss me, I just pushed him away and told him to leave me alone.<br><br>I ended up calling my mom and telling her what happened. She said she'd pick me up in 15 but when she got here he was asleep. I didn't want to wake him up so I just told her we'd talk about it later.<br><br>I'm so hurt, I feel so betrayed. I dont know what to do, I don't want to believe that it was a joke, but I also don't want to believe that my husband lied to me. I feel just so confused and hurt.
