This is a really complicated and heart - breaking situation. You may need to take some time to think about your relationship with your fiance. Consider whether this relationship is still worth continuing. If he can so easily fall in love with your sister, there might be some fundamental problems in your relationship with him. You could also seek advice from other family members or close friends who know your situation well. They may offer some practical solutions or at least some emotional support.
One way is to strengthen your relationship with your fiance. Spend more quality time together, do things you both enjoy, and communicate more deeply about your feelings and future plans.
Well, first of all, it's a tough situation. In a fanfic world, things can be really complex. If I were in this situation, I might try to have an honest conversation with both my fiance and my sister. I'd want to know exactly how they feel and why this has happened. Maybe there was some misunderstanding that led to these feelings.
You could start by expressing your feelings to your fiance. Let him know how much his new - found love for your sister is hurting you. Maybe he'll realize the depth of his mistake.
One great way is to involve her in your activities. If you like painting, let her paint with you. This will create a bond. You can also write her little notes and leave them in places she'll find, like on her pillow saying something like 'You're the best sister'. And don't forget to praise her when she does something good, whether it's getting a good grade or being kind to someone.
I babysat my little sister last weekend. We baked cookies together. She was so eager to help, but ended up making a bit of a mess with the flour. However, the cookies tasted great in the end.
One way could be to make her do extra chores. For example, if she's been mean to you, ask her to clean the dishes for a week. It teaches her responsibility.
It's not really appropriate. Beds are very personal spaces. You should encourage her to sleep in her own bed. It can also help her develop good sleep habits and a sense of independence.
My little sister is the sweetest. She has this infectious laugh that can brighten the darkest of days. I love her because she always shares her toys with me. Once, I was feeling really sad because I lost my favorite book. She came to me with her little teddy bear and said it would keep me company until I found my book. That simple act of kindness made me love her even more.
This is a more serious situation. You definitely need to involve your parents. They can have a long - term talk with her about proper behavior and the importance of privacy. Maybe set some clear rules in the house about where it's okay to be naked and where it's not.
