Search Results: forgiving after cheating

We've been together for 5 years.
The story: I've been her first (i had a couple gfs before) and she's been always happy with me. However now that she had stopped college she felt like she did miss a part of the fun lifestyle. Not really because of our relationship, but mostly because of her parents who were very strict. It was me who introduced her to the whole going out scene as i was living alone in the city where i studied. her parents allowed her to stay with me once, sometimes twice a month and then we went out. Now at the end of school she was going on a trip with some friends from school. All girls no boys allowed (most were single but there where 2 more girl with bf's)
Anyway they partied a lot drank,. so far so good.
One day she called me and confessed that while at a club she was drunk and got to dance with a stranger (which i don't mind as it was an all girl trip i did know they would dance with guys there) Everyone was dancing and a bit on a buzz so she joined in, and he kissed her and well she didn't stop him. this obviously pissed me off and i said some thing on the phone and hang up and ignored her. After a while (it was evening) i finally picked up and i could hear her still sobbing on the phone. It sorta broke my heart tbh, I felt sorry for her as this is the first time in her life she actually was out with girls alone in a club with drinking and... i mean she's 23 and i was the only guy she's ever even kissed (well till that incident ofc) I forgave her and understood that the fact she had been sheltered so long made her a bit oblivious of the dangers of drinking.. And i felt sorta happy she finally had let go for once and had some 'dumb party' fun. I told her it wasn't a big deal. She didn't want to go out that night so she stayed in the hotel and we talked on the phone all night and made up. after the trip she confessed that when they went out again she got drunk again and kissed a guy and gave him a hj. while he got under her shirt.
