ey yo son. Your girl fucked up. Ima give you the realest advice, not the most idealistic advice, not what sounds good, but ima be real as fuck.
It was your girls bday, a day where she supposed to be celebrating with you, but instead, she puts priority in doing other things, like coming to the restaurant with a friend, and leaving with a plan and pursuing her own plans and not "y'all" plans.
Now she went with her friend, who lives with her bf, who has another dude over the house. Your girl knew who was there, and went there drunk as fuck, looking to fuck. People gonna disagree but come on. Your girl is grown as fuck. Why did she go to her friends house with other dudes over, drunk, and didn't call and text. she a grown ass person and her friend took her phone and wouldn't give it back? yo that is a dumb ass excuse, and with it, she is disrespecting your intelligence. A grown person takes another grown persons phone and doesn't give her phone back and your girl ain't get mad and tell her like "yo give me back my fucking phone, I need to send my man the address" come on son. She played you, knowingly.
The fucked up part of it all is that this shit was planned in advance. Instead of making plans with you, she comes and meets you at a restaurant, with a friend, and leaves with a friend who got dudes over. Sounds like she came to dinner just to get it out the way son. You probably payed for dinner to. haha. damn that's fucked up.
find a new girl my dude. when grown people are in a relationship there has to be a level of respect and dos and donts. if she can't decide that going over her friends house when dudes are over on her bday is wrong, its best to end it.
Now, the reason she did what she did? 2 possibilities. either the relationship ain't fun and exciting to her anymore so she had to get excitement elsewhere on her bday, which means its time to end the relationship, keep its because of the atl vacation you took that people are talking about and she wanted revenge, and you don't wanna be with a girl like that neither.
@Charlie_danger is giving good advice but yo, realistically, on her bday, at her friends house there was two dudes, one was the friends bf, the other was a single dude, and they were two girls. it wasn't no party. 2 dudes, 2 girls, one of which is a grown person who gets her phone taken away by another grown person.
Its fucked up how it went down son, but you gotta end it. dont be a sucker.
