<human>: I'm not happy with her anymore.

I'm easily frustrated when talking to her about serious things.

We haven't had sex in at least four or five months. This is my own choice. I just don't have a sex drive around her.

We do live together, but our lease is coming up. I make enough to cover rent by myself.

I met someone new and I love talking with her. I've known her for about 8 weeks and have been talking with her for 2 weeks. She's 16. I'm not trying to have any serious relationship with her (obviously), but it was an eye opening experience. That's the relationship I want. I just can't have that with my current girlfriend.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I'm frustrated with my current girlfrriend, but I live with her and her best friend is offering me a contract job for lots of money. How do I break up with her? Should I break up with her?
