I'm so sad to say OP, that I TOTALLY understand how you feel. My DH has smoked all his life, he is now 65. He gave up once for about a year, but there was a stressful event, and lo and behold he went back to it. Recently he has had to go into hospital for surgery, and told me he knew he had to stop. He stopped for 4 weeks, then the 2 days before the operation, he gave into the urge, although only had 1 each day. He's now home from hospital, and the first time he was able to get outside (I won't let him do it inside), he was straight back on them. He was found to have Claudication in his legs 5 years ago, and was told that if he didn't stop smoking he would end up having his legs amputated. Even this didn't stop him! He is now due to have a stent put in his leg because of this. In reality, much as it upsets me, because I love him deeply and don't want to lose him, I KNOW he won't give up now, as if he was going to do it long term, he would have with the threats he's already seeing to his life, and now, to top it all off he has COPD! If I didn't love him so much, I would leave him, but as I do, I have to accept that it's his choice, hard as it is.
