I have this in my youngest daughters relationship. Her boyfriend is over mothered. I on the other hand always thought that being a good parent is knowing when to let go on time for all steps of growing up. So they have this problem of totally opposite backgrounds where he is this "worrying" type like his mother and my daughter being absolutely her own independent mature for her age person (both 19). It is so interesting to watch how they interact.
But for you brendannz I have only one suggestion. Think and act as if playing a role of and independent person. Soon you will be one. Fake it to make it
