<human>: Me (m18), her (f18)  K, so basically, met this girl, that I really connected with, enjoyed being around, solid 10/10, and all that good stuff, hung out with her for a few weeks, and essentially, we were a couple after that. We went out for 5 months( I've known her my whole life but we just recently started going out (like, the past year.)) Eventually, we break up, but still luckily are good friends, after all the awkwardness had been settled, she starts texting me again. However its to let me know that she fucked my best friend of sixteen years, and that she really likes him and all that shit, and of course, me being the complete idiot I am, help her out, because she was to nervous to ask him herself, so I get this relationship up and running, she thanks me a shitload, says "I'm the best" and shit like that and then hasn't talked to me since. And the worst part is, that we all hang out in the same social group, and I have to see them making out right in front of me 24/7. Fuck. How do I get out of this depression that this relationship is bringing me???
