<human>: Can you succinctly summarize the text in 1-3 sentences?

We have been together since late April.  I tend to fall for someone quickly but that wasn't the case here (this was actually kind of a relief).  However...here we are coming up on 4 months in and I wouldn't say I'm crazy about her.  I like spending time with her but, for example, if she or I go away for a few days, I wouldn't say I miss her.

I also get the vibe that she's way more into me than I am into her.  So much so that we had a talk a couple months in where I said that, if she had said, "I love you," to me that I wouldn't be able to say it back.  It was a good talk and she said she was in the same place...so great....but my position on this has not changed and I don't know that it will.

So...my two quick questions:

1. As someone who, as mentioned, tends to fall for someone fast and hard....do I just need to let this play out longer?  Is this kind of timeline really more normal than I realize?

2. If I am going to break up with her, what's the best day to do that?  On a Friday so she has the weekend to get over it or on a Sunday when she can just go to work the next day and get into a routine?  She has a weekend getaway coming up with some friends....wait until after that or maybe before when she can be around her friends for a while?  (clearly, I'm not often the one doing the dumping in the relationship....)
<bot>: Not sure I feel as strong about my GF as I should.  Should I break up with her and, if so, when?
