Hooking up with my [M23] year long crush [F26] in Costa Rica’s jungle [MF]

This happened about 2 and 1/2 years ago. As the title says its about me [23M] hooking up with my friend “Gabby” [26 F] in while in the jungle of Costa Rica. Its a bit of a long story that takes place over a year, I’ll post the longer back story in a comment. There is could also be a part two if people are interested that I’d like to write. This my first time posting here and even sharing this publicly, so hopefully I am doing this right and you all enjoy.

I met Gabby at a conference in San Francisco through a friend, Carlos, were both college students in southern California and this when my crust started, around October 2017. Carlos and Gabby dated for a few months and while they were doing so all three of us plus Gabby’s best friend went on a weekend trip in March. While I tried to respect Carlos and Gabby’s relationship, I got jealous one night after drinking, made out and got a blowjob from her best friend, which Gabby overheard in the other room. Carlos and Gabby break up soon after, but Gabby thinks I’m an asshole for not following up with her best friend. My friends were planning a trip to an animal sanctuary for four weeks in Costa Rica over the summer with “someone” who had already been there, I say yeah and buy my tickets, etc. Turns out that someone was Gabby and by the summer only her, I and one other person are were still going.
