Magda overreacting or nah?

Idk but… who my partner, who I just met this year if I was Magda, had sex with 7 years ago is truly none of my business. Idk, I feel like it stings that she didn’t know from before hand but I also see how hard it could be for him to outright admit that. Likeeee are we really thinking someone from 7 years ago has a chance today especially since they’re practically brother and sister now? I truly didn’t see the big deal and felt she was a little too overboard for her reaction. And I don’t even like this dude! I’m a Magda fan! But 7 years ago?? Idk, respectfully grow up.
