<human>: For background I'm 19 [F], and he's 24; this is my first relationship, while he recently got out of a serious relationship. We have been dating for 2 months, but were friends before that. However, for the past couple weeks I've been feeling dissatisfied with the relationship, and thought about breaking up.
  
He was the first to use the "love" word, a week into the relationship, and I responded back because I liked him and wasn't sure what else to do. I've come to realize that while I care for him, I don't love him; and he certainly seems to care and be much more emotionally dependent upon me. But since I started using that word, how can I stop using it; and if I do break up with him, how can I justify myself when I told him I once loved him?  

Also, for future relationships, should someone professing love in the first week be considered a red flag?

Can you give me the gist of the text in a nutshell?
<bot>: How can I tell a guy I want to end the relationship, when I recently told him that I love him?
