To preface, this is the first girl that I've maintained a relationship with for more than 1-2 dates (i.e. I have a decent amount of inexperience). So I [27M] started seeing this girl [26F] regularly a couple of months ago (1-3 times per week) and it's been great for the most part (i.e. interesting conversation, good texting banter, and solid sex). The issue is that she gets mad at me on at least half our dates and often tells me she's unhappy about something I did. Due to inexperience, I could see this being me and not being used to being extremely considerate of someone else but I'm really not sure.

There are three primary times when these blow-ups happen: after hanging out with my friends, my lack of (jealous) response if she's out with another guy (even when she prefaces by saying it's not a date), and times when we're back at her place instead of still being out (many times these things occur in pairs). A few examples are as follows:

The first time a friend third-wheeled a date (inadvertently), I apparently did a poor job of considering her emotions. It started with my friend needing some spare keys and being at the same location my date was supposed to start. As I was on the phone with him (trying to find him in a crowd), this girl saw me and I gestured at her to follow me but continued to talk on the phone with my friend. Shortly after (< 10 seconds) I found him and introduced them both. At that point she asked if he wanted to join us for a drink and he agreed. So the three of us ended up going to this bar and there were a couple of times when the two of us got into an intense conversation. While I agree in retrospect this was bad, I'm not sure she had to keep chiding me for it several dates down the line. Things such as: "I can't believe you would ignore me like that with your friends", "you really need to step it up", and "seriously, what the fuck was that?" were all uttered in reference to that night (each time me profusely apologizing).

After the first date, I kept getting on OKCupid to message a few other dates I had lined up. While I too thought her and I had a great date, I just changed cities and didn't think we'd go from zero to serious (although we did have sex that first night). She was clearly not in the same mindset. When she told me she had another date lined up, I just said "alright" or something to that effect but figured it was her life to do whatever. Later on (after she had her date and slept with the guy), she kept asking why I hadn't tried to stop her from going and telling me that she wouldn't have slept with him if I had just bothered to text her while she was on that date. I knew she liked me, but getting all angry and trying to stop her seemed stupid to me (and something that a junior high student would do). Maybe I should've shown more feeling but honestly I was still trying to figure out if I liked her liked her and I didn't want to stop her from exploring. In particular, she's coming off of a long (> 5 year relationship) and I didn't think getting super serious was good for either of us.

As a last example, we seem to have ways of going out. While I don't mind drinking hard (> 7 drinks), I do get intensely tired when I combine alcohol with staying out past midnight. So bad is my tiredness, that I can literally fall asleep at the bar if I get sleepy and drunk. Now that she knows it's due to tiredness (apparently she thought I just had a bad tolerance), it's gotten a little better. That said, on rides home she'll say things like "I can't believe we're going back so early...but it's all good", "ohh...you're so tired" (condescending tone), "going to be able to stay up and fuck me?". In these cases, I'm wide awake and I feel like she's being sassy for no reason.

Anyway, there're plenty of similar kinds of things (more times spent with friends where she feels I ignore her, more times of her going on dates, etc) but I think these cases exemplify the crux of all these issues.

I realize my own narrative is biased by me telling it (her side is probably that she's with a guy who fails to show lots of interest but enjoys have sex with her). Still I can't shake the feeling that she's blowing a lot of things out of proportion. Since I don't have lots of dating experience, it's been hard for me to read...

Any thoughts on how this sounds? Is there a chance it's all on me?

tl;dr Girl I'm dating is angered by my lack of living up to her expectations and I'm trying to figure out if I'm a dating asshat
