This aspect is very difficult to deal with, and could end up hurting your relationship unless you take preventative steps from the start. The problem is, there is a certain level of control that has existed between you from the beginning -- maybe your lover criticizes you for the ways that you dress or behave in public, or even for the dreams that you hold dear to your heart -- and over time, those criticisms take on a dimension of their own. They become tiny cuts on your soul, ones that hurt you, even if you try to ignore them.
It might even feel like your partner doesn't like the real you, and worse, you may come across as feeling the same way about them -- without even realizing it! You might feel as if they're trying to discipline you all the time, never letting you simply be the person that you are. This is no fun in a romantic relationship! Love makes us so vulnerable, and for someone that supposedly loves us to constantly tell us what's wrong with us just doesn't feel good. If you two can be aware of this tendency from the start, your lover can curb their urges to criticize you, and you can work at recognizing what that criticism really is -- an attempt to control or improve you, which isn't really appropriate. As long as you learn from this interaction, this could end up being a positive experience for both of you.
