It's clear that this situation is causing significant distress for both you and your husband, and it's understandable that you would feel frustrated and betrayed by the cycle of promises and relapses. Here are some points that might help in addressing the question and providing support:

Understanding Addiction: Smoking is a powerful addiction, primarily due to nicotine, which is a highly addictive substance. It's important to recognize that quitting smoking is often not just a matter of willpower. The physical and psychological aspects of nicotine addiction can make it extremely difficult for someone to stop smoking, even... if they have strong personal reasons to do so.
The Cycle of Change: Change, especially when it comes to addictive behaviors, is rarely a straight path. The Transtheoretical Model of Change outlines stages that individuals go through when changing behavior, including precontemplation, contemplation, preparation, action, maintenance, and relapse. Relapse is a common part of the process and doesn't mean that progress hasn't been made or that future attempts will be unsuccessful.
Personal Motivation: For change to be sustainable, it often needs to come from a personal desire to change rather than external pressure. While your husband understands the strain smoking puts on your relationship, his motivation to quit needs to be internally driven for a greater chance of success.
Communication: It's important to communicate your feelings without blame or guilt. Expressing how his smoking affects you and your relationship is valid, but it should be done in a way that is non-confrontational and from a place of concern and support.
Support Systems: Quitting smoking is more successful with a strong support system. This can include counseling, support groups, or smoking cessation programs. Encourage your husband to seek out these resources and offer to support him in this process.
Managing Expectations: It's crucial to manage your expectations regarding his quitting process. Understand that relapses can and do happen, and it doesn't mean that he doesn't care about you or your relationship. It's a reflection of the difficulty of overcoming addiction.
Self-Care: It's also important for you to take care of yourself. The stress of dealing with a partner's addiction can be overwhelming, and you may benefit from support as well, whether that's through therapy, support groups for loved ones of those with addiction, or simply ensuring you have your own space and activities that help you manage stress.
Boundaries: It's okay to set boundaries around smoking, such as not smoking in the house or car, to protect your own well-being. Boundaries are not about controlling the other person's behavior but about taking care of yourself.
Professional Help: Encourage your husband to seek professional help. This could be a doctor, a therapist, or a smoking cessation specialist who can provide him with strategies to quit smoking and to deal with the psychological aspects of addiction.
Patience and Compassion: Finally, patience and compassion for both your husband and yourself are key. Quitting smoking is a journey, and it's important to celebrate small victories along the way.
It's a challenging situation, but with the right support and approach, it's possible for your husband to work towards quitting smoking and for both of you to work through the strain it's putting on your relationship. Read more

Hello! First of all my apologies for this late answer, I never received a notification from the website.
About your husband's situation, smoking is a really difficult habit to quit, many people even go to therapy because of it. Behind an addiction there are emotional issues that must be worked, at certain point smoking is giving him what he might be needing (in a very short-time), like lowering his level of anxiety. For instance, this goes beyond avoid bothering you, his need is stronger. He might be struggling with trying to quit and make you feel respected, so you must stop thinking that this is about you. Tell him that this bother...s you but you have observed how hard this is for him, so talk about his emotions, about what worries him and ask him how you can help him. Read more
