I'm getting married this year, tricky situation has developed where one of the guests also attends a gym that I go to. I have walked in to the gym this week and said guest was there but completely unaware that I had walked in behind her and her friend. I hear their conversation and basically this guest is having an affair with another guest who is invited with his wife! I am in shock. I won't go into detail in case it's outing, but they won't be aware that one another is invited to the wedding yet, only the gym guest out of the 2 has had their invite up to now. I have told my DP I don't want them at the wedding now, but how on earth do I explain that when it comes around given that these are people who are close enough to be expecting an invite! It's none of my business what they do I get that, but they both have husbands and wives that this would shatter! What do I even do? I don't want them at my wedding, I feel awful not telling their partners as they are both close to us (not related). WWYD? I wish I was wrong but it was definitely what was being discussed, and there are reasons that I 100% know which man she was talking about which I won't say on here, and also what she has been getting up to with him 🤯🤯
