<human>: She and I are (were?) best friends. We could talk about everything and anything, we spent all our time together, we loved each other unconditionally. We went into first year of University together... Unfortunately, she isn't very good at meeting people, so I introduced her to my friends. Now we have almost identical social circles.

Because of this, as time passed I felt I was seeing her too much. She gave me the space I needed, which worked for a while (she travels for work). Recently, even without seeing her for up to three weeks at a time I still felt like I didn't want to be around her.

Over the past few weeks I've been considering breaking up with her. The only problem was, I knew I still loved her deeply, despite not wanting to be around her as much. This confused me, so I didn't know if I wanted to go through with it.

I stopped telling her I loved her, which she obviously noticed. This morning she asked me why, and I (stupidly) told her not to ask me that question. After she spent some time crying she asked me again, so I said that "I didn't think it was fair to tell someone you love them when you don't know if you want to be with them". After some more tears and talk, she begged for a break instead of a breakup. I said it was unfair to have her wait for me to decide if I wanted to come back, so in stubborness I broke up with her instead.

I felt relieved, but now feel extreme regret, sadness, and shame. She texted me a few times askiing me to explain, and I don't know what to say. I also find myself wanting to be "on a break" instead of broken up, but I feel like that might make it worse when we do fully break up. I just have no clue if breaking up was the right decision.

Can you condense the text into three sentences or less?
<bot>: I stopped missing my girlfriend when she travels, so instead of "taking a break", I broke up with her. I don't know if it was the right decision because I still love her. I need advice on what to do.
