<human>: Provide a brief overview of the text.

I've been with my gf for over three years, without any major incidents or drama. There's been no indication of a bad relationship in my opinion at all.

I have, however, in the last month had some serious doubts as to whether or not I want to be in this relationship. These feelings are completely one-sided and egoistic. I have no serious complaints about my girlfriend, other than that we're both busy people and sometimes only meet once a week. I have never seen this as a major problem though.

I feel restricted, and somehow bound by my relationship. It started a few weeks ago when I got a pretty major crush on a girl who goes to my University (different Uni than my gf goes to). I got over the crush more or less, but it left me with a huge feeling of doubt. Am I seriously committed or not? Do I want to be?

On Sunday night I told her I'm having doubts and even hinted at a breakup. She got really sad, and so did I. We decided to sleep on it (both at her place), and talked again Monday morning. I still felt like I had to be honest, and I told her I still feel like I want out. When I was leaving things were pretty bitter. I felt really awful and turned back to hug and kiss her and tell her I'm sorry I'm dragging her through this. I left saying that I would contact her once I've had some time to think about all this, alone.

Now I'm really fucking lost. I can't decide what I want. And I know I'm hurting my gf really bad by being this indecisive. I've at least damaged the relationship pretty badly already by bringing this up. 
I don't want to hurt her like this, but should I really ignore these feelings I'm having?

I need help figuring out what I really want.
<bot>: I told my gf I'm having doubts about our relationship. Her reaction affected me a lot, and now I'm confused. Need help.
