Is my friend being a total *****?

Her SO just got back from the military to visit for 2 weeks. They hadn't seen each other for 6 months. But everytime I ask that we should hang out or do something she always says to make sure my SO comes with me too.

And she's always saying that she wants alone time with him like to rub it in my face to not come around and see him. He's my friend, too. It just seems like now that her SO is home she doesn't want me around. But if he does something to annoy her or make her mad she comes running to me to go pick her up right away.

Idk am I overreacting?
