^ But Liam has had a tough life, he's a famous for crying out loud. I can't imagine being really famous because the constant pressure, work load and being harassed by fans. I don't think Liam ever really looked at his life before he lost his wife and child. Maybe he didn't want to face reality, he probably knew deep down that his life was going down the drain, he was so messed up in the drug business. But I think once he had a friend like Belle and his wife finally said enough is enough was a wake up call. Liam has apologised in a geniune manner, he really means it and you can see that he's willing to put in the effort to beat his drug addiction and get his life back on track even though his lost the two most important person to him and then the only real friend he had (Belle) died.
Liam is a very interesting character
