Relationship Goin Down????

So... I'm in a relationship with this guy named Tyler... And recently it's like we can't find somethin to talk bout like its always "wyd" literallyyyy EVERY 2 minutes... We don't have anythinggggg in common.. Hes a gangster and does drugs like weed and stuff.. And I'm nothin but country... And I have feelins for another guy and I don't wanna be untruthful  with Tyler and say that he's the only guy I like but then I HATE hurtin people. Also, it's like Tyler don't care anymore bout me or us and we have nothin to talk bout or say.. I guess what I'm askin here is should I break it off with him???? And please don't judge I don't know what to do really.
