<human>: Warning: Not so good english...

Hello Reddit,

I know this is a recurrent subject, but I really need a voice to tell how to proceed with this.

We've dating for 3 and a little more years, but lately (a month or so) I don't feel the same way about her. I'd rather be with friends or alone than with her. She's very dependant and she needs lots of attention. Everyday I get the "Do you still love me?", "I don't want to lose you", "Are we going to be together for a long time?" and it kills me. I don't even know how to answer lately. She's in love with me (she has told me), so a break up will kill her, but maybe it's the only choice. 

The other thing is there is so much stuff that we share: same college, same carreer, same classes, same group of friends. We even have a little business together.

Please help me. This is my very first serious relationship and I don't really know how to breakup with someone, and with someone who hasn't done nothing wrong, cares and loves me. I just feel like a dick.

Summarize the given text in a few sentences.
<bot>: I'm not longer attracted to my girl, and I need advice in how to break up, where and how to handle the consequences.
