Have a deeper emotional intimacy with your best friend?
Why be in a relationship if you have someone else you'd rather hand out with all the time and share your deepest secrets with them? Are you even in love with that person or are subconsciously in love with your bestie?
Yes you can. I've come to realize I love my friend more than I have anyone I've ever been in a relationship with. However, I don't think I'm in love with him as I see him more as a pet. :x It depends from person to person though.
