Stuck..

So basically I'm with this guy and we've been together foe two weeks sksks don't judge lmao. But basically We never do anything and he never respects my decisions and I didn't want ppl to know that me and him were together and he didn't care, just told everyone. Then he's always like small talking and stuff. Now I'm starting to lose feelings for him. I'm starting to like my ex (I broke up with him because I thought he was avoiding me,now I found out it was rumours) so yeah please help
