Has anybody noticed any major patterns in terms of texts that girls who are and aren't interested send after a date? I'm asking partly because I just had a date with what I see as an IOD text after a date where she seemed really interested.

So had this date with a HB7.5 who basically said towards the end of an 8-hour date (mini golf, carnival rides, pizza, board game, costs evenly split per her initiative, yes I tried to take it to a more intimate setting but she balked) to text her with 2 hours warning to go hang out in the next few days doing something that is free (she agreed to hang out at her place then), before I leave for Christmas, whichever day works for me because she won't have plans. We spent a lot of time making out towards the end, felt her up. Near the end she said she'll have to get used to how "nice" I am, in response to (I think?) me stroking her hair a lot. I spent a few moments thinking about how much I wish she hadn't said that, then said, "Really, you joked about having a penis and I grabbed your crotch to make sure you were joking. I spent the whole night calling you "animal lover" because you misspoke about your job as a biologist," she laughed and we agreed it was funny how I grabbed her crotch. Then at the end she expressed surprise at how well that went. I gave her a blank stare, and asked what she means. "Well I tend to expect the worst. That you'll hate me or I'll hate you." I said, "You don't seem to hate me too much," she smiled and kissed me. We were 2 hours past her bedtime, she had to get up at 4. I told her to text me when she got home.

Her: "Home safe"
Me: "Just got home safe too Was fun - look forward to seeing you soon"
Her: "Vey good first date goodnight"

Me: Shit, she can't spell, and she didn't reciprocate the seeing you soon part...

I think it's annoying as hell that girls who aren't interested text that they had fun, so that's why I add the "look forward to seeing you soon" part because I've never had a girl say "me too" to that part who wasn't actually interested. But should I take it as an IOD, as in, prioritize other girls, that she didn't reciprocate the part about looking forward to seeing me again? I already have today booked, but am considering trying to take her up on her offer Monday. It's sooner than I would normally try, especially with mixed? signals, but I am leaving for a week on Wednesday/ Tuesday and she suggested it... should I wait, just let her contact me, or contact her Monday after she gets off work?

Man, don't beat yourself up, date went well, you certainly moved around a lot, you made out and the proposal to hang out at her place is basically an invite to close her... her text answer was cool, she didn't pay attention to say "me too" but it's no big deal... so don't wait up, call her tomorrow and drop by her place with a bottle of wine... strike the iron while it's hot and give her something to remember the end of 2013 for...

Yep you were completely right, except I was listening well enough to know she prefers IPAs over wine, haha. The day after our first date she texted me in the evening:

Her: No more keeping me out past my bedtime, I'm so tired!
Me: coming from the girl who asked me to take her back to her car while she's still sitting on me? .. It's a deal Cinderella.
Me: so tomorrow I'll come over and beat you at some more games. what time and what's your address?
Her: Haha, I should be off at 2 but ill let you know if works running late. I'm at [her address], you better not be a serial killer! Ill be really mad!
Me: not being a serial killer... check... well you're easy to please aren't you? looking forward to it
Her: Pretty much, but you have to put up with all the sarcasm too...
Me: oh I can handle you... by the way assuming you don't want to smell like the river when I arrive, so if you're getting off at 2, I'll show up at 3?
Her: Yeah, time to shower would be nice, 3 sounds good

So I show up with the old school video games we agreed to play, and a 6-pack of Total Domination IPA, which she loved. We had fun, she's really into me. And yes, there was the f close despite her being on her period. I hope to see her again, but even if not, mission accomplished.
