I enjoyed this a little bit more than Exciting Times, I think, but it still just falls short of 5 stars for me. 

I think my main issue with this, is just like Ava in Exciting Times, one of the main characters in The Happy Couple, Luke, can't/won't make a decision to save his f**king life! Now, to be fair, I think this book does deal with that better than Exciting Times because it actually acknowledges it as a thing that's happening, and how it leads to other people getting hurt, even if that's never really Luke's intention. (Luke is also not a passive character in his lack of decision making, he actively chooses to do some things, bad things, but still, he makes things happen) 
And, on reflection it's probably an accurate reflection of a lot of people and relationships in real life. So it's not that I don't find it believable, or relatable, there's just something about that kind of character that irks me a little. I also found that Luke's section of the book veered at times a little into sounding like the author just wanting to make loads of little points about things, and while most of them were pretty interesting and/or accurate, that section of the book just slowed everything down a bit too much for me. 

I will acknowledge though that any "problems" I had with anything here are definitely me things, and I liked way more about it than I didn't. It really feels like a forward step from Exciting Times, and I'm excited to see what Dolan does next.
