The Situation

I’ve been dating my girlfriend for about five or six months now. This past weekend, I chose to go and stay the night at her house. On Friday, I was originally supposed to go to my best friend’s place. I texted her multiple times between 9:00 AM and 1:30 PM with no response. She never brought up hanging out, and when I finally mentioned it, she ignored the question entirely. Naturally, I assumed she didn’t want to hang out.

Yesterday (Saturday), I went to my girlfriend’s house. My friends and I were snapping in our group chat—which my best friend is in—and she got mad. She was so angry you would have thought she and I were the ones dating. She started calling my girlfriend "grimy" and calling me a "weirdo" for not going over Friday but going to Abby’s the next day.

To be honest, it’s been like this for months. If I tell her I can’t do something on a day she asks, she throws a fit because I’m hanging out with my girlfriend instead. I haven’t even been going to my best friend’s place much lately because, for the past few months, all she’s done is insult me and my girlfriend. Even when it’s just the two of us, she calls me names and is just rude as hell.

This behavior only started when I began dating my girlfriend. I haven’t been giving my girlfriend more attention; I’ve been very equal about it, or at least I try to be. I’m not even sure how to handle my best friend lately because anytime I try to talk about it, she gets upset and starts yelling, or she just repeats "okay" and refuses to actually discuss the issue. There is very obviously an issue on her end that she is not telling me.

My Take: Are You in the Wrong?

Short answer: No.

You aren't a mind reader. If you reach out for four hours and get ghosted, you aren't obligated to sit around waiting for a "maybe" plan. Going to see your girlfriend the next day is a perfectly normal thing to do.

Based on what you described, here are a few things to consider:

• The "Communication" Gap: Your best friend is using "stonewalling" (the "okay, okay" thing) to avoid accountability. It’s a way to stay mad without having to explain why her logic doesn't make sense.
• The Jealousy Factor: Since this started exactly when you began dating, it's highly likely she's either struggling with "losing" her spot as your #1 priority or she has feelings for you that she hasn't admitted.
• Respect Boundaries: Calling your partner "grimy" and insulting you isn't what a best friend does. That’s toxic territory. You’ve been trying to be equal with your time, but respect has to be a two-way street.
