I did not want to tell my husband. If i could have done it with out him knowing I would have done. At first he was a bit (not sure) shall we say. But today he has been with me for my appointment and sat in with me and was very supportive, apart from him making the odd wise crack (through nerves)
My op is this saturday and I just can not wait for it. If you tell him our important it is for you and he sees how the op is performed he will probably be fine. I bet his concerns will be that as long as you are safe and well.
Good luck,
