Story: I visited my country's capital 2 weeks ago, where I had a pretty good weekend. Went out solo saturday made 2 bros from Spain and bagged a girl from neighboring country - sadly her friends kept cockblocking us, whenever we were making out or I was grabbing her ass. She asked my number and left, but came back cuz I hadn't responded - I tried isolating her and we made out I was grabbing her tits and ass in the street but her friends kept blowing up her phone telling her to come to them and not go with some guy she doesnt know in a foreign city. I was too tired at this point to bother and went home, and we exchanged a few texts. The next day I text her, that I'm on getting the train home if she wants to say bye, she complies and comes to train station where we walk, talk and make out a bit. She says how she regrets not going home with me etc. and how it's sad we'll never meet again. I tell her to come visit my city, we are neighbor countries after all, she happily agrees. After 1-2 hours we say bye. She texts me in the train how it was nice to see each other and see you in "X/my" city, I reply "glad you came "name", see you in "x city". She responds: or in "x/ her" city. I reply "maybe afterwards;)" she responds "we say so:)" I like her message and no communication since

I usually try to not spend any time texting girls. But in hindsight I realized that it might've been a good idea to maintain a friendly rapport/comfort level, to increase the likelyhood of her wanting to come visit me here in a foreign city. What are your thoughts on this? Should I send her a message now or wait it out - since it's only been 2 weeks since she was in my country.

Never been in this situation and not sure how to best proceed, any advice?
