If your mom is nice to you she simply protects her assets. Her behaviour towards you is in no way an indicator on how attractive you are for potential partners from outside your family.
Her behaviour towards you however may be an indicator on how attractive you are for potential partners inside your family.
I'm kind of surprised what gets downvoted these days.. do people actually not know that humans are imitation learners in almost every social and scientific aspect? đ¨
In the same vein I'm shocked how little reading comprehension people have these days (such as this comment) and how people and how quickly people jump to align any information with their worldview. The post even said "majority" with no indication that the father wasn't around. For example someone that has two siblings, both sisters would fit that category.
