Hi, I'd like to help you with your question.
First I want to say how sorry I am about your loss. It sounds like you and your husband had a wonderful and fulfilling relationship.
When someone grieves such a loss, it is a very personal and private process. Every person is different in how they grieve. And the range of emotions can very greatly. You can feel anger, sadness, deep depression, regret, even disbelief. Some people can take a short time to grieve and others can take years.
What you are experiencing is the last stage of letting go. The image people may get of letting go is allowing the memory, experiences and even the very essence of the person drift into the past. But that is not what happens. Letting go is allowing yourself to live your life with grief no longer as a constant companion. It is allowing yourself to feel yourself again. This does not alter your memories and experiences with your husband. They will stay the same.
You may also be experiencing guilt at moving on. If you enjoy your life, what does that say about how you feel about your husband? Does that mean he was not important to you? But it is quite the opposite. By living your life, you are doing what he would want you to do. You honor his memory by moving on. It will not make you forget because he was such an important part of your life and who you are today. He lives through you and the relationship you had together. When you think of your life, most of it was spent with your husband. He is woven into your life. So leaving him behind is not possible. It would be like forgetting most of who you are.
Try this- write out a letter to your husband explaining how you feel. Tell him about what he did for you, how he affected your life and what you want to keep with you the rest of your life. You don't have to do this all at once. Write as you think of things and keep it until you feel it is done. This will help you identify how you feel but also it is a way to "communicate" and express how you feel.
If you find that you get stuck and cannot move on, consider talking to a counselor at least short term. Your doctor can help refer you to someone. A therapist can help you find your way through your feelings so you can go on with your life.
I hope this helps you,
