You go shopping with your boyfriend and his sister. They have a pleasant conversation, but their attitude towards you is a bit indifferent. Are you jealous?

No, after all, he and his sister are flesh and blood and have been together for more than ten years. Family affection and love cannot be compared.

Maybe your boyfriend didn't pay attention to some details, so he ignored you a little, but we girls are particularly concerned about these things. But in fact, this is nothing. You can also blend in and talk to them. Chat with his sister more, and then the relationship between the parties will get better.
