I basically lied about my entire past to a girl I was seeing. And then I married her.
You seriously lied to her the whole time? Did you lie because you wanted to marry her?
Yes. I also wanted to have sex with her
It is wrong to lie just to get married to a person. That would mean the whole relationship is built on a lie. You need to tell her the truth.
I would if it wasn't so boring and uncomfortable. I have to make time for it
Please find the time soon. The longer you wait to be honest with your wife the worse her reaction will be.
