Is he real or not, or playing safe? Will I let go or not? Will I keep the friendship or not?

I've been so generous with my friend (guy) 'coz it's in my personality, but when I didn't have the chance to continue giving him cutie stuff 'coz there are so many things that I have to consider, we seldom talk now like we used to; even if we're both busy, we could find time to talk before. Some things have changed. I don't understand. One thing, he is afraid to tell me his story; his darkest side 'coz he doesn't want me to receive bad impression about him. Will I keep the friendship or let go of him?
