<human>: Can you give me a shortened version of the text?

My GF and I  have been dating for 5 months now. We were friends for a few months before that. Initially she got a crush on me, and asked me out. The first month or two we dated, our relationship wasn't that great tbh. Mainly because I didn't treat her like a girlfriend. I'd leave and go home after we fucked, showed up over an hour late to our first date, ditch her during out hangouts to go get high with my friends, etc... we had some good times, but overall I felt nothing towards her so I was kind of an asshole. 

After some time though, I started to like her and act a lot better and more like her boyfriend and we started having even more fun, and she started to REALLY like me, I know cause she'd tell me that she "really really really liked me" multiple times, and that "I was the best guy she ever dated" 

Heres the thing though, she told me she "loves me" but she said that she wasn't "in love" with me. I didn't know how to react so I was just like "ok". But now she always says "I love you" before we go to sleep, or I leave or something. 

I never say it back because I still only kinda like her, I'm no where close to feeling like I love her or being able to say it back to her, and honestly, I feel kinda bad about it. I'm afraid that she expects me to say it back sometime soon, and I know that its not gonna come for a while, and I don't wanna hurt her, but everytime she says it I  just kiss her or awkwardly nod my head....how should I handle this? Do you think I should tell her to stop saying it to me until I feel I'm ready to say it back, or should I just keep doing what I'm doing?
<bot>: My GF always tells me she loves me, I can't say it back and I know I wont for a long time. How do I handle this?
