Give advice to a guy in need, does she or does she not care? Options

[creamyxlicious]

I'm asking this on behalf of a guy I kinda know,
he's a real nice guy and he's with my friend Rose.
I'm running low on advice to give him..
So I was hoping you guys might have some..

The current problem for this guy is,
He doesn't know what's going on in his relationship and what to do now.

He says "well, in private, we act like a couple and sometimes in public, but ever since Rose had a talk with thuy (thuy likes rose as well), we been kinda distant. She told me we had to be apart a bit because my grades are sinking and I need to focus on studying.."

Kev says he often asks what they should do about their relationship.
She asks him what he wanted, and he asks her the same and they kept asking each other until kev told her

"well, I want you."
She told him "well you already have me.."

Do you think she's serious about Kev or if she just wants to get out of the relationship?

[side note: she usually have relationships barely lasting a week]
