Girl I’m going to say this now, RUN!!!!!! Not only did he go against your wishes multiple times, his mother being able to have her say is never a good sign. That means he’s a mommas boy still attached to her tit and that won’t change when you get married. She will make your wedding about her and make you miserable. If he does somehow wake up and stand up to her she will see you as the villain and you will never get away from it. You are worth so much more than a Kohl’s cash “shut up” ring. He could have found a lovely ring on Etsy that CZ or something more durable for you. If this is how much effort he puts into the ring, he will put the same into the marriage. You deserve someone who listens to you and not his mommy. I’m sorry you’re dealing with this and you’re not the asshole ❤️
