So my situation is that I really messed up this connection I used to have with this girl. To keep a long story short, we knew each other for awhile because I knew her brother, but didn't spend any time with her up until a few weeks ago on a road trip back home. A couple of days ago I drunk text her and said things like....bitch, lets play, my brain is confused....the last one my friend got on my sn and said. So after that whole mess I apologized by leaving her a voicemail and sent several texts online about where we're at.

I think I'm DLV myself, but I really didn't want to game her like that so I thought an apology was appropriate. She never replied or called so I'm now assuming she wants to distance herself from me. I know there was a major connection we had in the car, I can just tell- we had good vibes. I'm afraid I lost it after these past days, she also gave me an IOI because she wanted me to take her out to dinner after the road trip.

Anyways, can you guys help out?

Never apologizing is just being an arrogant prick. I think you did the right thing to apoligize. At least you gave it a shot and was genuine.
Before you can move on to anything is just to wait for her reply and try not to let this bother you too much.

Okay in this kind of situation it was best to attempt to apologize but never leave a voicemail. You should always make sure you're actually talking to her then apologizing because then you can get instant results as if she is either still mad at you or forgives you so therefore you don't have to think about this stuff all day whether or not she still likes you.
I think she's trying to come up with something to say thats why she hasn't contacted you back. When she does, you can try and rekindle the vibe by going out and doing something fun.
