Frustrated

So me and my boyfriend are basically taking a little break, I've noticed he's been changing a lot and started treating me differently so I asked for a break, he's been really "manning" up since then I've heard and he's even gotten a promotion with his job. Anyways, I don't want to officially get off of our break yet because I feel like he takes advantage of me sometimes and doesn't really appreciate me and I feel bad but I'm giving him a hard time so that he realizes he needs me and appreciates me more so when he tries talking to me I blow him off and act like I don't necessarily want to talk to him, but the thing is I'm starting to get BEYOND frustrated and I don't know what to do, I would NEVER cheat on him, so that's definitely not and answer to my problem but I don't wanna run back to him just for sex. Help!
