quitting smoking

Ladies, I need help! My bf is quitting smoking and I need some ideas on how I can help him through this process. It's only day two and I'm already finding it hard to remain supportive. I want him to quit, but at the same time I am very emotional and he has made me cry atleast once an hour since he's quit. It's not even that he's being very mean, it's just that I'm extremely emotional... I would appreciate any advice in this situation! Thanks in advance!
