So sorry that you find yourself here. Sounds like you have been having a tough time.
First off, buy a copy of DR. Read it and then read again. Post often- you will get great advice from people who are expert and successful DBers.
You're doing the right thing by not trying to initiate contact now- he has asked for space and as hard as that is, you need to give it to him. And when you do speak, no crying, pleading, pressure, or initiating relationship discussions.
It's hard, but you will get through this. Oh, and make sure you visit the success stories- they are a great source of hope.
Walk on, walk on, with hope in your heart. And you'll never walk alone.
