One thing with relationships - no matter how many people are involved - is that communication is key. You have many talents, but mind reading and precognition aren't two of them. You three have been friends for a long time, even before this all became official, so I don't think she'd not want to be around you if she said she wanted you to come. Maybe she's caught up in figuring out her part in this that she hasn't given thought to how you would feel. She's a great girl, but Allison can sometimes act a little too independent without noticing.
