Maybe he is hurting too. If he was close to your brother, then it could be a really hard thing for him to deal with... Let me start with saying I am so sorry!!! If you want anyone to talk to and listen to you, send me a message on this site. I will listen to you and give you all the advice you need. Next, give ur man some space and talk to him when he cools down about the whole thing... Remember, other people are here for you too. I'm here. I can be someone to talk to if you really need someone.
