<human>: First time posting here, apologies if this doesn't work. 

I have two friends, I'll call one "Erin" and the other "Sam." She is 20, and he is 19 and they have been dating for around 2 years, they have been dating since high school.

Erin has moments when she breaks down because Sam is a sucky boyfriend, because he can't emotionally connect with her. It's not his fault, but it really takes a toll on Erin, and when she talks to him about it, he just says "sorry" and they go back to the way they are. She broke down crying to me and said that she feels like he is "settling for her" and that she sometimes thinks it would be best to break up with him, but she doesn't want to because she thinks she will never meet anyone else. (Erin is a beautiful lady, and could easily have any man she wanted). 

Basically, I want her to end the relationship, because it feels unhealthy to me, and I want her to be happy with herself, which she is not. How can I go about this? Or do I just stay out of it.

Give me a shortened version of the text
<bot>: I basically want to tell my friend to break up with her boyfriend, but I'm not sure how to, or if I even should.
