Is NOBODY wrong in the post ? POST : Recently my boyfriend and I both started college. We still live in the same town and we both have jobs.

Over the past few weeks I've been noticing that he's ignoring my texts a lot. We don't text much, usually just to make plans to see each other. 
Lately I've been sending texts along the lines of "hey do you want to hang out next Saturday?" and he'll open it but not reply. Usually I have to send another text like "hey I really need to know if we're gonna hang out so I can plan my weekend, get back to me please?"

At least once I've had to send a third message telling him I need him to reply and that it hurts me when he opens my texts and doesn't reply. Only then would he respond.

We had a fight about this last weekend. He says he doesn't reply because he doesn't always know if he'll be free to hang out or not and because he's just too stressed out with college and work.

Am I being too harsh?
