My Story - Separated 1 Month

[bluMorn]

So this morning, some friends of ours message us on facebook saying they are having a last minute crawfish boil, and would like us to come if we are not busy. Of course, they don't know about the separation, and I was just agonizing about what to say (it was a group message, and I knew H had already seen the message too). A little while later he asked to see if I was going, that he was going and bringing my SS and nephew. I asked would you be okay with me going, and he said of course, so I said I was (I wanted to anyway). He said he'd be there about 5:30. I'm a little nervous because I have no idea how to act. I plan to get there earlier than him (he has work). These friends are a little older than us, and are great people, and I'd really love to get their advice on this.
