This song is about a relationship with somekind of bad girl. so it all makes sense. Actually in all the song including the part "And it really makes me wonder if I ever give a fuck about you" he wants to seem to her like he didnt care about her (but in deep he wanted her back)
"Give me something to believe in
'Cause I don't believe in you anymore"
Its actually about her doing smthing wrong and he cant believe her anymore even if he wants her back
