<human>: Can you provide a brief rundown of the text in within 3 sentences?

I [23M] just recently graduated college and moved in with my sister because it's conveniently close to my new work. She's always been an isolated/introvert type but I realized it even more living with her. We were talking about relationships and future which we usually don't speak of... Anyway, she's completely too shy to get in the dating world. She's been on probably 2 dates in the last 5 years since her last (and only) boyfriend. She's a great, caring, beautiful woman and love kids - works at a children's hospital. She's great with our 2 yr old niece. She needs to take that first step to get back on track. So many guys would be lucky to have her but she thinks "it's too late". I want to help, need advice!!
<bot>: My 27 year old introvert sister will not socialize, has given up on having a family of her own. Looking for advice!
