<human>: Can you provide a brief rundown of the text in within 3 sentences?

The other day while on the phone I think my girlfriend almost said that she loves me (I'm currently away on a 2 week business trip). She started to say "I lo..." then changed her departing comment to "good night, I miss you." 

So I'm thinking that when I get back from my trip she might say that she loves me. We are pretty close now and we have the best communication that I've ever had in a relationship. I'm very happy with where we are but I'm not in love/falling in love quite yet. I think she has stronger feeling than I do. 

If she does say that she loves me I don't want to lie and say it back but I also don't want things to get awkward and change. I'm really comfortable with the relationship. What should I prepare for?
<bot>: I think my gf almost said that she's loves me but I'm not quite there yet. What do I say if/when she actually says it and I can't reciprocate the sentiment quite yet?
