I did, a long time ago when I was much younger. I didn't feel good about lying. Every time I did it, it chipped away another little piece of my self-respect.
I ended up being so frustrated that we would argue all the time, because he wasn't allowing me to be the person I wanted to be.
He gradually ground me down, so I was allowed to see fewer and fewer people.
Then eventually, when I had no friends left, one day, after yet another row, he left me because he 'couldn't trust me'.
At no stage had I even looked at another man. I had lied to him and been found out though.
I realise he will sulk, but in your position, I would not lie. I would go and tell him the truth and point out he was being unreasonable. I would not be with a man who wanted me to be someone I wasn't.
He is showing you he doesn't actually love the real you. When he realises who you really are, he might leave you and you will blame yourself because when he tells you he can't trust you, you will have no defence.
