back after 10 weeks of recovery and need some help

[Doingitright]

What do you do when....W snoops and sees:  reciept from lunch, money order, and appointment scheduled for Dr and she says...

You can tell me what is going on.  What did you do for lunch on Tuesday?  Answer...I went to lunch with co worker and best friend ( male).  I thought you said he was on vacation til Wed.  I thought so to but I was wrong only til Monday came back Tuesday.  W thought I was having an affair.  

W what about money order...Money order to pay for Counslor visit as I forgot my check book and they do not take cash.  Went to post office and bought money order to pay.

What about Dr appoint is to see pyscologist?  To ensure I do not slip into a funk while going through this ordeal.  So I will be switching Drs.

I said I won't be cheating on her as we are still married.  That will never happen while we are married.  I need to get through what is occuring and I am not where she is yet in not wanting the marriage.  So I want to remain healthy both physically and mentally.

Talked about her anxiety episodes in the past few days and I said the medicine alone will not make things better.  She needs to see a professional to work trough some of her troubles.  She agreed that she needs to see someone and that her lexapro isn't the sole answer.

Did I do wrong in this exchange?  I feel like I practiced what I have learned thus far.  Any pointers as to what ways to do better?
