What does this mean? (read description)?

My friend told me to add this guy on facebook (fb) and I found him cute so I did. He accepted the request a few minutes later. I'd occasionally spy on his social networks because I was interested in him and then my friend dared me to text him and I was really scared that he wouldn't answer ect: but I did it.
I texted him on fb when he was online: "Hey "
I waited and on facebook it tells you if the person saw your text and it wasn't seen yet after 15 mins it says : "seen (with a tick) and the time" he doesn't respond,so I'm thinking why didn't he respond.
I sent him that in March. It's now April and no reply. After the next day that I sent him that I didn't care and lost interest. All I want to know is "Why didn't he respond?"
On other social networks girls have asked him about sending him texts ect and he said he was open to getting to know new people ect. I'm so confused.
I'm not into him anymore but I just want to know. "Why would a guy do that?" at least say "Hi" back or say "Kinda busy" or "I can't talk right now" if you're not interested.

Thanks in advance.

he didnt respond cause he didnt want to

He must have been busy to reply and then he must have forgotten about it. If you really want to find out send him another message. If he doesn't respond then simply he's not interested.

it means he wasn't interested in getting back to you.
