How to deal with someone that never opens up to you even though you've been trying for years?

Question

but they want to hang out with you

Answer 1

Let them be; why would you persist? That is just nagging.

Answer 2

That's just the way they are.  Accept it, but still be nice to them.

Answer 3

Stop trying.  People are the way they are and we just have to accept that fact.  If someone wants to open up to you he/she will do so in his/her own time.  It's not something you can make happen, no matter how much you try.

Answer 4

It seems like you put a lot of worth on people who "open up to you".  It is interesting you have been attempting to make him/her share information with you.  Look at it this way, If you spent years trying to pump him/her for information and she/he still wants to spend time with you, he/she must be an extremely tolerant and patient individual and you should be pleased to have such a mature and independent individual as a friend.
