Eric,
when you are lonely it is very easy to attach yourself to one person when they pay attention to you.
I hope as a Christian he truly cared and befriended you out of love and concern.
I am one who makes excuses for people.
I would like to think that maybe he is going through a hard time, maybe is overwhelmed with school, church, homework, etc....
I can't tell you how many times I have thought of people I care about and have every intention of contacting them but I get sidetracked and procrastinate.
They are on my mind yet THEY think I have forgotten them.
Maybe this is the case.
Please reach out to someone with YOUR kind friendship now.
There are others who feel just like you who need love, attention and friendship.
Just look around.
May God bless you and help you through this~
