Maybe I'm the only one who saw it perhaps this way, from reading your post word for word, but I'll say it anyway, in case anyone didn't hit upon this possibility...

It sounds like he started liking someone at camp, but as he was still in a relationship with you, he asked why you haven't said you love each other in the 2 1/2 months you've been together...

From what I read, again, it sounds like your response was simply "It takes time"...

Some of us guys know exactly what we want out of a real loving relationship, and don't want to waste a lot of time on someone debating if there's any love there or not...

They want do bluntly know, do you love me after this long or not... Otherwise, I'll simply move on, and give my heart to someone else who does...

It sounds like he wanted a real relationship, with the actual word "Love", while you couldn't make up your mind, and wanted to keep him waiting, which is simply not his goal in love, to wait...
