<human>: So I guess most of the pertinent 'relationship' details are in the title. She has been my friend since freshman year of college. I think I'm just going to jump into the question and then add details via edits or comments based on what people think they need.

She recently asked to take a day off work since she is house sitting for a week which I am more than happy to do. But she also asked me to go on her family's vacation with her which seems very anti-FWBish. 

So I think she's wanting more, and while I'm somewhere in the middle of what I want, I at least want to talk about with her to make sure we're on the same page before something awkward happens on her family vacation.

I had plans last night to meet her for some drinks which was a perfect opportunity to bring this up. So she texted me around the arranged time and I texted her back and then didn't hear anything for two-ish hours. When I heard from her again, she apologized and said that her phone has been having service problems with sending and receiving texts all day. Texting since then has spotty, but not negative or overall different.  

This seems fishy in today's world, but it's also a pretty a paper-thin excuse so I'm inclined to believe it. Plus, our plans RE: house sitting and vacation are still on. 

Should I continue as planned? I think I'm just looking for general insights and opinions.

Can you condense the text into three sentences or less?
<bot>: FWB invites me on family vacation which seems to be a signal she wants more. I'm on the fence. Some odd behavior last night. Want some general insights.
