Texting him too much?

If he doesn't respond that much to texts anymore, it's most likely not because he's lost interest! He's probably busy, with family or friends and living his own life. It doesn't mean that he has lost interest in you. A way to tell if you're an obsessive texter could be that you're texting him a lot more than he texts you. Boys are not as "obsessive" as girls and are normally more down to earth, so he may not want a huge inbox full of messages from the same girl expecting a reply. He obviously likes you but try not to take it personally; he most likely thinks you're great! If this starts to effect you a lot in the long run, don't be afraid to ask why he's doing this. If he's good, he'll try to understand and resolve the problem.

The fact you're even asking the question is, in fact, the answer to the question.

I do the same exact thing. I have no idea.
