To give a bit of backstory here, there's the girl my age that was my girlfriend in junior high school or so (5 years ago). We split up shortly before I moved away but we've stayed loosely in touch since then with periods of lots of communication and some dead periods. 

A few months back, we got in touch again and asked for my number so we could text (easier for her). She said we should "catch up" sometime, but then she got all busy and went to Europe for a while. My last text to her was in early May, and now in early July she sent me an unexpected "hii".

I know I'm probably blowing this out of proportion, but for some reason I'm optimistic about this and want her to get to know me again, since we've both gone through a lot since we last met up. Should I just casually reply to her text and go from there?

Girl I've been texting and talking to for a few months sent me a "hii" afterwards. Should I assume she was interested in talking to me after
