I need some advice..

So my boyfriend & I have been together for almost 8 months. Recently he told me that it's not the same anymore, are love is fading & that I could do whatever I want & that he'll do the same he said he's been talking to his friends ( girls) that whatever I do, won't affect him. But tells me that he loves me & doesn't wanna leave me & but he doesnt care what happens to us.. Ever since he's just like whatever he doesn't pay attention to me.. I love him so much he my first eveything.. But not going to sit here & be stressing over it..what would you do?
