My husband jerked off while I was "asleep in our bed"

So my husband works long hour days and we have been trying to conceive for 2 years without any success. 
The other night I went to bed and I heard the tv which woke me up. I got up and I could see the light in toilet. The tiles are so shiny that you can see the reflection and YES there he was doing it.
I feel so sad and I can't even think about it, makes me feel sick. 
Please tell me what you think.
