She wanted to sit in the pub with him the way Sam did with Steve, the way Matty and Karen had done last weekend with their boyfriends, to hold his hand as they walked down the street, to be able to smile in public at him, not this controlled, agonisingly formal behaviour. It struck her, this week in particular, that she was completely isolated. She couldn't talk to him, she couldn't talk to her friends, and she didn't know when that would change. And she couldn't do anything about it; she was weak, because she loved him too much, not that that was weakness, but - she was powerless.
