Is he your boyfriend? But you don’t think he wants to hear from you? What kind of boyfriend is that?
If he’s your boyfriend then text him. If he thinks you’re too needy, the relationship is over already and there’s nothing you can do about it. He’ll figure it out sooner or later. Just be yourself and talk to him. That’s all you can do. Don’t try to pretend to be someone you are not. It won’t work. You don’t want a boyfriend who doesn’t want you to be you.
If you just want a trophy boyfriend, then by all means, wait until he calls. But you’re missing out on finding the real deal, if you waste time on someone like that.
