I came out 3yrs ago & have lost many friends but I assure you it was worth it.
Those that I lost obviously weren't good friends & those that I kept are some of the best people i've ever known.
Some people were so shocked by my news that in spite of them being good people they didn't know how to respond, they were literally too stunned for words, I had to be the one to re-open the lines of communication, several of the people who didn't know what to say said that they had many questions but were afraid of offending me by asking, it wasn't until I told them that no question would offend me as much as being ignored that they realised that they had made the wrong choice by not getting in touch.
You say that you told him 2 weeks ago & are now afraid of rejection, I think that you should either phone him or go see him in person, if these people reject you then they never were true friends but if you don't atttempt to speak to them then you'll never know.
Right now you are letting your fears dominate your actions, fear feeds on uncertainty & the longer you leave it the harder it will be to break this cycle. Bite the bullet & take action, only then will you know if you have been rejected & until you have an answer you will be trapped in this state of uncertainty.
If the result is good then you'll probably feel silly for doubting them, if the result is bad then at least you'll be able to start dealing with it instead of worrying yourself sick.
If the result is bad then you'll always have support in dealing with it on this forum but I ask you to stop letting fear rule your actions for the sake of your own mental wellbeing.
The friends i've kept are amazing & the friends i've made since coming out outshine the so called friends that I lost.
