My..complicated relationship

The whole story is really long and I am not here to bored you guys.. So there is that boy. Him and I know each other for about a year and a half and we are communicating on facebook, but we have met 4-5 times. He liked me from the start and everything seemed to go pretty well, even tho he assumed our relationship as "friends with benefits" (we only kissed). But there is also that one old dude, who puts some kind of pressure on the boy which affects him badly. I can feel how he slowly changes and start behaves like the old dude...He dont want to listen to me, attacts me when I tell him there is a problem and everything slowly became little different.

I thought we should break the relationship...today he texted me and send me that song called ``That was yesterday`` The text has deep meaning, but on the other hand it is just a song..he does not tell me anything really...

I'm just very confused and need some advice..what should I do...what shuld I say...

thanks for the reading
