Little Update: Trip is over.
I had some fun on my trip. Also with another girl (only kissing). Being in a big city i also booked two "high class" escorts for the first time and my first threesome(only 2 hours for sex). And you know what: It was awesome!!! Had some hours in between meeting friend 1 and friend 2, and just went for it. Expensive, but very beautiful girls and awesome time. I dont want to use this to substitute my game, but in this moment it was just perfect. Normally I am loyal, but if a girl isnt loyal to me, i feel entitled to do my own thing...
Funny thing is, that we wrote sometimes. But she always initiated contact. I kept is passively, answering her questions and throwing back a question from time to time.
After the trip she complained, that i didnt write often. I only answered, that i was out with my guys and dont check my smartphone all the time.
Also made it clear, that in a relationship i want my girl to spend AT LEAST as many vacation days with me as she does with her friends.
Keeping the corona situation in mind (hard to get girls atm), i let it flow now, see what happens, wont invest that much anymore.
