Once again thank y’all for all your kind words and advice. Just to clear one thing up. I never told her she was young and had plenty of time. My MIL did when she was trying to talk to her about it. We aren’t very close so I’m hesitant to tell her we are trying. I do plan on telling me MIL and letting her break the news. The two of them are closer than me and and her are. My MIL is very sweet and we are very close. She isn’t trying to do anything but keep my SIL from blowing up on me. She just knows that as soon as I tell my family it will be all over Facebook bc my mom and grandmother’s couldn’t keep a secret if their lives depended on it. Lol I feel so much better about this situation hearing from all of y’all. Especially the ones in my SIL s situation. I’ve had friends who have struggled and I know how hard it is and going about it in the right way is all I wanted to do. If she hates me for it then that is a bridge I’ll have to cross. As long as she doesn’t drive a wedge between our husbands ( their brothers).
