Shall I help my crush get back with his ex?

I have a crush on this guy (let's call him Blake) who just got out of a relationship around three weeks ago. I have been having feelings for him for quite a while and we have been talking a lot recently. Last friday, we kinda hit it. He flirted with me a lot and I have caught him staring at me a lot in class. He sometimes wait for me and we walk together in the corridor. For a while, I thought that he likes me back but, then, yesterday he told me that he's still in love with his ex and he's empty without her and needs my help to get back with her. A part of me does not want them to get back together but another part of me feels bad for him...I understand that they just recently broke up and moving on is really hard but I really don't know what to do...when he flirted with me I thought it meant something...I guess I was wrong...

How does he need your help to get back with his girlfriend? This guy sounds like he is bad news. But I'm just curious, what stunt is he trying to pull on the girl he supposedly cares about?
