I agree.
I don't think everyone defines levels of emotional intimacy and boundaries the same.
at the same time I think inherent relationship expectations come in to play as well.
I'm not a modern day romantic. As stated previously, I'm more into my man and my relationship than anything else but I'm very traditional in a sense that there are very definitive spousal boundaries and expectations. While I love being able to be open and tell my partner my deepest most intimate thoughts, I dont want to tell him every little detail about every little thing that happens. I don't know if that's a personality factor or what but my my personal reservation is similar to my mom in that I believe there's a time, a place and a person for everything. My SO means everything to me but he's not my everything ya know. I'm also someone that appreciates arranged marriages.
