I wish you have a happy life  (or, "May you have a happy life")

Last month I began to play WeiXin.  You use your phone to meet many people and have a chance to be friends with them. I met a person who lives in the USA,I thought he could help me with my English.  We talked about many things, such as family, friendship, jobs. But now we have not talked for many days,no reason.I am a very shy girl,I have tried to talk with him but he does not respond.  I just want to meet and talk .That’s OK .I think now it's hard to find true friendship.I  hope you have a happy life.

很好!

I have corrected your verb tenses.  You are telling a story about something that happened in the past, so your verbs should be past tense.

One more small thing: remember to put a space after a period (.) or comma (,)

And yes, 真友谊 is hard to find, but it's worth being patient and looking for!  你找到!
