It was LOL as the kids say. It is just the currenty obsession with non sutble comedy means someone has to write a joke that has been done millions of times before before anyone feels it is worthy of a laugh.
I suppose it was slightly lazy ignoring the boyfriend but it doesn't matter as my point is that this is way above anything else that has been written all year. Like the Royle Family there were so many subtle naunces that most viewers would not pick up on but nontheless the writers had gone to the trouble of including them and so this puts it far any Sunday night comedy drama. In reality these geniuses have taken a twee story and turned into to high art.
