My Man Just Defended His Ex – Leo and Rebecca Buzz Question

Leo and Rebecca Buzz Question - Me and my girl saw my ex the other day and we didn't say much about it. Well, yesterday she brought it up and said 'yeah, we say your FAT EX the other day and I replied 'Um she's NOT FAT!' ....Yep I Did. Well, now my girl is giving me the silent treatment for saying that. Does that deserve the SILENT TREATMENT???? Wow.
