Loving relationship or Codependance?

Curious what people's views are reflecting the difference between a relationship where two people are in love and when the relationship crosses over to being one of codependance? There have a been a few discussions about it recently and it's caused me to think bout it in terms of my relationship whereby:

- My partner and I love each other very much;
- We are very open and expressive of one another and communicate frequently, even when we are not together;
- When we do communicate, we are open and honest and listen to each other;
- When we are not working or traveling for work, we want to spend the majority of our free time together;
- We like hanging out with other couples socially, although given how much time we are apart, we rarely do;
- We do at times hang out, independently of one another, with our respective friends;
- We both work and generate income, pay our respective direct expenses independently of one another, although I typically cover the expenses for activities we do together given I do earn more,
- Given we both travel quite a bit, we are apart from one another just as much as we are together, probably half our time,
- When we are not together, he is always on my mind, I am sad he is not with me, and I am always thinking about him; and based on our discussions, he seems to do the same thing.

As I look at my relationship, it seems to be a healthy loving relationship. When would it cross the line and become codependent?
