<human>: Can you condense the text into a few key points?

Before you say *I'm just a teenager, and that I probably have hormonal complications which are triggering the effects I am experiencing now* please just hear me out.

The two of us have issues, just like any other human being on the planet, but the way we confide in each other differs.

No matter the problem - whether it  be personal, regarding our relationship, or foreign - I always bring it up directly with her and do my best to confide in her and her alone, thinking it would be a wise decision to strengthen the trust between the two of us(?).

Now, despite my best attempts to comfort and console her, she doesn't always come to me with her problems. Instead, (I'd say about 50% of the time) she sees a good friend of hers (another guy) and talks deeply to him about things. I tell her that I am completely and utterly open to anything she has to say, even if she just needs someone to ramble to and release heat or has to confront a problem of *mine*.

Now would probably be a good time to mention I do have trust issues and can be rather overprotective at times because of situations outside of our relationship, but I admit to these problems and would like to fix them in the long run.

With that being said, I don't know whether or not I'm simply overreacting to the fact that maybe she needs another person to talk to, or that my effort alone isn't good enough, or possibly even that she's more comfortable with this guy.

I just don't know, and that's why I'm coming to you, Relationships.

Is it okay for a person to find advice and comfort in someone other than their partner? Is there an extent to which it becomes negative rather than positive (for either party)?
<bot>: Girlfriend talks to another guy for comfort/advice instead of me (50% of the time) and doesn't see anything wrong with it.
