<human>: Can you give me the gist of the text in a nutshell?

My best friend, who is 24, is currently dating her neighbors( close friend of hers) 17 year old brother. They shared their first kiss in February of this year, and have been seeing each other ever since. She is someone who wants marriage and kids, and she wants these things pretty badly. 

So what is going on his her head that is saying," yeah, I'll get these things with a 17 year old high school senior." 

About 2-3 months in she asked him about labeling their relationship. He told her he doesn't want the title yet, but isn't interested in seeing anyone else. She goes to his house for holidays and his parents know they are dating, and her family knows as well. 

I've seen her in this situation before. She dated a guy long distance for 9-ish months, lost her virginity to him, and when she brought up the title thing he gave her the same excuse. Then she dated a guy who is a known player a year later, and another after that. I have no idea why she keeps dating guys that won't commit to her, or who make no sense IMO.

She gets upset whenever I bring these things up. I know it's because she doesn't want to hear it, and doesn't want me to rain on her parade, but am I wrong for feeling like she needs to hear it, even though she doesn't want to? 

This current guy, again, is 17 years old. Yes, it is legal where we live by the way. 5 months is a decent amount of time to know whether or not you want to be with someone. Again, remember, she wants a committed relationship, so what is she doing with a 17 year old who doesn't want the title?
<bot>: She has been dating him for 5 months and he doesn't want the title. I think he's giving her the run around, but she won't listen to anything I have to say.
