I agree with what the posters above said. It's up to people if
they want to make time for you. It happened to me before, maybe i
can share with you guys:
I used to have a very close friend, used to even call him "best
friend". I would have known him for 10 years now if we had kept in
contact. I last saw him about a year back & after that, i swore
to check him off my friends list. Thing is, it doesn't matter how
long you know somebody, they can just be making use of you the
whole time.
He used to hang out with me really often, like maybe 3-4 times a
week. He didn't really have much friends then, & as i found out
from his later actions, was just making use of me as a stepping
stone. Then after he entered a new stage of his life, a new school,
he started hanging out more often with his new found friends &
we slipped contact.
I tried contacting him but like you TS, he was BUSY. I tried
many times but it was always the same reply. So after some time, i
got the hint & just stopped contacting him altogether. If
someone is keen on keeping a friendship, they will HAVE time no
matter what. So, if those people keep making the same excuses, they
just aren't keen on hanging out with you.
Do what i did, i totally dropped that person off my friends
list. If i bump into him anywhere, i wouldn't even acknowledge him.
Be smart, not desperate. Now i'm so much better off, i have a bunch
of buddies who hang out with me very often.
Go make some new friends & open up more. Be friendly &
i'm sure you will find friends very soon!
