A great story. Thank goodness the heroine ends up with who she did. I did not like the character of Arsen at all. He was selfish, egotistical and immature. Their affair really did repulse me (I think it was supposed to) especially because of the heroine's fragile state. She was mentally and emotionally unwell and that is why it was so sick and wrong what Arsen did. They used each other in the worst way possible and thank goodness she realised what a fool she had been in the end. 
 Cathy used Arsen to forget. Pure and simple. She admitted it on several occasions and this is what I found so confusing. WHYYYYY couldn't she see that what she had with Arsen wasn't real? Her husband was a wonderful man and I am glad he found it in his heart to forgive her and move forward. I felt like there were two versions of Cathy. The real her (which was the one we first became acquainted with) and the false Cathy (the one after she suffered yet another heart breaking miscarriage)this version of herself was the one she used to hide behind and this was also the point where I started to lose sympathy for her. I could empathise with her agony, grief and loss but could not understand how she could be so blind. She was using Arsen to numb her own pain and this was made blatantly obvious throughout the second half of the book. 
 He became her own type of drug, she didn't feel alive unless she had her fix. This is NOT love, it's addiction. 
 I'm glad she eventually snapped out of her selfishness and managed to redeem herself. I'm also thrilled her and Ben managed to conceive their own baby and move forward from their horrible nightmare. The ending left me shocked and overwhelmed, I would have felt more sympathy towards Arsen if I had respected him but because I didn't... I suppose I felt like he got what he deserved. Husband and wife could have their happy ever after without any further input from him. 
 I think this story is mainly about the lessons we learn in life. Catchy certainly learnt hers and I think for that reason alone, the reader will end up respecting her in the end.
