I think the best way to show your wife how much you really appreciate her is to find some time to be alone together. Then, look her in the eyes, hold her hands and tell her what you felt. How much you love her, and tell her you are very lucky and blessed to have her in your life. Tell her that you may never said so much for the past two years but you noticed and felt her support and love and that you appreciate everything she has done to you.

I know that men are not so open and have a little difficulty showing or saying what they felt so I am sure your wife would really appreciate it if you open up with her and tell her how you feel. It makes them feel that they are a part of your life. Sometimes women felt left out when their husband suddenly becomes silent. It is difficult for us to really understand and accept that it is the nature of men to be silent sometimes especially if they are dealing with some problems. So, I guess she would be more than happy if you say how you feel right on her face, she will feel you are connecting with her.

Then, show her how you feel by surprising her with a breakfast in bed. You can also do some household chores, I am sure your wife will be very happy. If you have a garden with flowers, then you can pick the best flowers that you can see and give it to her.

There are many simple ways to show appreciation, but the single most effective way is to just say it to her and be sincere with your words.
