How do I support my man when he pledges?

[ILoveMyMan]

I love my man with all my heart and feel that he is my soulmate. He is pledging Alpha Phi Alpha and is about to go online. I am not Greek and need to know what to expect this process to be like for us and our relationship. Already I am having a hard time with it (its hard not to get upset when we're cuddling together about to go to bed and he gets a call and has to leave), but i try to understand. However I need help in knowing what to do and how to feel when this happens, since from what I hear, it's about to get a lot worse. I love my man and will be there for him through this, but I also need him to be there for me through this. He said himself that he doesn't have any idea of what this is like for me, so he doesn't know how to help me. Any advice for both of us??
