Have you checked for any other marriages ? A lot can happen in 10 years 
I have checked for other marriages. But I have Hannah Richardson (nee Strudwick) in the 1871 - 1891 census (she died in 1900). As she's a widow in 1871 I'm assuming Thomas did die. There's a death registered in 1865 which I believe could be him. I'll be ordering the GRO certificate to confirm this.
