There is an expression which states “out of sight, out of mind” -- and since you’re never off her mind, she’s never going to let you out of her sight. This makes it near impossible to live the life of a normal man, because every move you make is being watched by your partner.
Why It's Harmful: An overbearing and constantly in-contact partner doesn’t allow you the freedom to live a life apart from being a couple. You can’t grab drinks with friends, go on a long run or even run to the corner store without answering a list of interrogating questions. This forces you to either answer those questions every single time or lie about your location. Lying is never good in a relationship. Lying every day is toxic.
