I swear to god if you're butthurt because I won't tell my parents...
You text me out of the blue after three days' worth of silence asking me when I'm going to tell. How bout when I feel that the time is right? Listen, my parents don't trust you, which is mostly thanks to breaking up with me in the past for stupid, illegitimate reasons. If you're pissed because I'm not saying anything to them, then that's on you. I really don't want my parents to think less of me for getting back with you. Plus I believe you've forgotten how our roles were reversed when we first started seeing each other and you didn't want to tell your parents about me but mine were perfectly cool with it.
Yes, I want to be able to hang out with you this summer, and that's another thing. How do I know you're going to follow through with that? Hell, telling them might be in vain if you can't hold up your end of the deal. If that happens, not only will you have gotten me in trouble, but it would've been for nothing.
I really don't know what to do right now; you're making me frustrated. Don't try to rush me into dealing with issues that involve my family. I think it's fine that you don't want to "go behind their backs" but you need to, no, you will give me time to sort things out.
