Really need advice

Please be kind in your comments, but my husband and I just got married in February and our relationship took a turn for the worst. At the same time our relationship cracked I met this guy at work who has been an amazing friend but I also developed a crush on him and what he talks he wants to give his wife and everything in the future. This coworker also made it clear that him and I weren’t going to be in a relationship or anything such but I felt for a moment that I wanted him. So now I don’t know what to do and of course everyone tells me I’m a bitch and my husband doesn’t deserve me and maybe he doesn’t, but divorce is not something I want but it’s also hard to get back to what we had .. any advice is appreciated. Thank you 🥺
