you were engaged to your fiance Derek and everything was fine and happy or so you thought until you saw on your mom's social media post a photo of your sister and fiance's marriage certificate and another one of him holding your sisters baby bump you were very confused so you casually commented a "?" Your mother replied quickly

Mother: "don't be selfish! Your sister is just going to marry Derek until their baby is born and then you can have him back!"

You felt stunned and your fiance also commented back to you

Derek: "yeah don't be like that I can be yours after my baby is born it's not that big of a deal"

You felt hurt and betrayed not knowing what to do so you turned of your phone

(What do you do now?)
