I would suspect that what you might be looking for in your relationship is intimacy...and a sense of connection.

Just because you're having sex with someone and lend them moral support doesn't mean that there's any intimacy in the relationship. It doen't mean that there's any connection.

Without intimacy there IS a desire for a connection... Something IS missing.

There is so much MORE to a relationship than simply sharing ones company, sex and moral support. What THAT describes is nothing more than "friends with benefits" and not a mature, loving relationship.

Talk with your partner and let her know what you think and what you want.
