I told him I was insecure and he just ignored it?

So basically, I'm having issues with accepting the fact that I'm surrounded by fake friends and don't have any real ones, so tonight my friend keeps texting me and I told him he was a compulsive liar, (something he is but can't accept and I hate it because it makes it hard for me to trust him). So I end up feeling guilty when I just want him to say he actually ares about me and I said "I'm sorry for being a douche earlier, I'm just insecure" and he just ignores what I say and goes on about something else.

The thing is, he said something along the lines of "I see you being one of my best friends for life" and yet he fails to pay any attention when I say these things, whenever I say something that's basically just a cry for help (I get extremely depressed and lonely a lot), how can he say he wants me to be a life-long friend when he doesn't even care about my feelings?

We're both 17, he's a straight guy, I'm a gay guy, there's nothing else to it really.
