Sometime I lie and tell my fiance I'm busy. In reality I just want to be left alone so I can watch The Office.
Does this happen often? Does she frequently bother you when you're trying to relax?
Yeah, she does.
Wanting to have alone time to relax is understandable but you shouldn't be lying to get it. She's the woman you're going to marry so she should be able to understand when you want some alone time to relax. Lying is just going to make things worse in the end when she finds out.
Come on, it's not such a big deal. Who cares?
It's a big deal because you should not develop a habit of lying before you're even married. Honesty is one of the most important aspects of a marriage. I hope you'll have an honest talk about this issue.
