Girls please don’t sugarcoat it! This girl said she would travel abroad with me, does that mean she’s interested?

So my girlfriend (ex now) and I just broke up about a week ago.

I went to a concert with two of my girl friends, one of whom I've had a crush on for like 4-5 years. We have a ton in common but the timing was never right and I haven't really made a move.

I don't know if she knows I'm romantically interested, I think she HAS to since her friends both know I had a thing for her.

*These past few days were a lot of fun. We took two good pictures together. There were a bunch of things where we were talking about cool things going on and she said "yeah we should do that that'd be fun!" Not over the top enthusiastic but definitely was interested in doing more (going to my cousin's concert, comedy club, etc). She even mentioned visiting my house. I told her about my two week trip to Europe and she thought it was so cool! I said "you should come with me" and she seemed pretty interested in going! It'll be next June, but we talked about it and she said to give her my itinerary and she would really consider it.

I don't know if she's ever showed this much interest in hanging out one on one before... It has to be romantic interest right?

She doesn't know I'm single and I didn't bring it up, so maybe that's why she wasn't super over-the-top ecstatic to hang out. It was more "yeah that'd be fun!" I was annoyed because one of her friends said "I could give you (name) number he is moving to the city" and she wasn't opposed to the idea, so wasn't sure if she just didn't like me.
