<human>: I like my girlfriend, we have been dating for about 6 months. Things are good between us and I like spending time with her, and sometimes, it is what I look forward to the most on some days. 

However, she has recently told me that she loves me and I just don't love her back. I don't think I can ever love her, or anyone for that matter. Either way, I did something I now think is stupid and I told her that I love her too. 

How do I tell her that I don't really love her and that I only said it because I didn't want her to feel bad? Ideally, I don't want us to break up because I do like spending time with her and finding a new girlfriend would be a big pain.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Girlfriend told me she loves me, I don't love her back but told her I do. How do I undo this?
