F-ISFP sending mixed signals to M-ENTJ

I had a thing with a this ISFP. We had a lot in common and unquestionable chemistry. There was unfinished business when circumstances separated us.

A significant amount of time passed, years, and then we reconnected. I contacted her and invited her on trip. She was excited to hear from me and came. We had a great time. We really hit it off. We were both surprised with how much we connected. So much so that she planned another trip to see me before we went back to our respective cities. We spoke a few times thereafter, but then she ghosted me. She did not follow through on the trip she planned.

After a month of ghosting, I reached out. I offered understanding as I know she can withdraw. I offered to see her again with another travel plan (I’m a digital nomad). She was very appreciative of my understanding, apologized for ghosting, and expressed excitement for the new plans. She accepted the invite. Then she proceeded to invite me on an adventure of her own in a couple months.

Now we’re days away from my trip, and I haven’t heard from her. I doubt she’ll come. I don’t more than double text as I don’t wish to apply pressure. It would be great to have her out for company, but it’s not the purpose of my travels. I’ll enjoy my travels regardless.

So I’m confused. On one had she’s traveled for me, we really connect, she invited me on a trip, and is excited to speak to me when we do speak over text. On the other she’s horrible at texting, has ghosted me and flaked on a trip in the past. Now it looks like she’s going to bail again. This was a second chance, and it sucks that this will be the end of the line. Never dealt with something like this.

ISFPs, what is this?
