I think this is a comedy of errors in several ways.
I agree with Howie that she was really running quite late (and her assuming this is OK based on prior interactions/sex/intimacy). So my quick take on that is y'all don't know each other well enough yet to know each other's pet peeves/expectations.
This is plainly one of Howie's pet peeves. Frankly I am sympathetic to wanting to see the band & for her not to run so late but you won the battle & lost the war on this one.
Best approach? Be flirty, try to escalate for sex (as you did). Since she was coy about that you pour a libation or glass of wine & you visit with her while she gets ready. You tease her but you relax. She's running very late but she's making an effort for you. You take that one on one time to build rapport.
Then you go out & enjoy the evening. In the future you know she runs late & to either mention it or adjust accordingly (I like
@Roober 's approach, perhaps you demote her or dump her after a la
@guru1000.)
The best way to manage punctuality going forward is to make your expectations clear in advance. I'm dating a retired military man. Punctuality is his thing. If we agree to go out at 7, he's sometimes there 30 minutes early, ready to go. Obviously I'm not yet ready. So I'll invite him in and he'll say "take your time - I'm early" and I'll pour him a drink & we'll chat while I get my hair finished or whatever. This has got me trained to understand not to lollygag about (I am famous for running late), and that on time/early is important to him.
For NYE he traveled cross country to take me out. It was our first weekend trip/hotel stay etc. The hotel put on an elegant c0cktail hour from 5-6pm with complimentary wine to kick off the evening. He was ready to go downstairs at 5:30. I was still finishing my makeup. So he said "I'm heading down, I'll get you a drink, see you shortly." No discussion, not up for debate, very pleasant...but he wasn't going to wait.
I got done about 15 minutes later & went down. Naturally my date is already engaged in conversation with two attractive women (Of course he is...that's his MO), one of the women was hitting on him outrageously... He passed me my wine, introduced me to his new acquaintances and we all chatted for awhile. No overt communication needed about the timeliness thing whatsoever. We went on to enjoy a lovely evening.
So from a "game" perspective he took the opportunity to display how important punctuality is to him and also took the opportunity to reiterate his SMV in my absence.
Fortunately I read all the subcontext and am not jealous at all. I understand him and how he operates. A less confident woman might have been irritated by what he did on several levels...I was not. Later in the evening he expressed appreciation for the grace & lack of jealousy I exhibited; and I acknowledged that I wasn't ready to go on time. No harm no foul.
I wonder if the angry texts from your date
@Howiestern weren't really anger at you setting boundaries, but even if so they weren't set smoothly. You could have set your boundaries more covertly (like my date) and your date could have joined you later at the venue too. The main thing is to be pleasant & direct about it in a gentle way. If it's very early on in the dating process as I mentioned at the outset of the post...you guys are still feeling out what each other's expectations are. We are between 4 & 5 months in so know one another better...but it's never too early to covertly manage an expectation like this.
So that's a little food for thought.
