Anyway, I'm in college, and one night this past semester was at a party and ended up talking to this guy for a while. We were both probably a little buzzed, but not drunk by any means, and he seemed nice, so when he asked for my number before I left I gave it to him. Couple of days later, he texts me and asks if I wanted to get coffee sometime that week, I thought why not, so we decided on a day/time. When I got there and saw him, he seemed confused/like he wasn't expecting me at first, and them apparently realized his mistake and tells me something along the lines of "Oh my gosh, I'm so sorry, but I thought I was meeting someone else tonight." WHAT. Turns out he had met another girl, who I happen to actually know very well and also happens to have the same name as me, the next night at a bonfire they both went to, and somehow got us mixed up in his phone and thought he was texting her the whole time. Needless to say, I no longer had any interest in being on this date/hang-out/whatever you wanna call it with him, but I was super awkward about it and stunned and didn't know how to react, and he was the same way, so before I managed to get myself together enough to figure out what to do he had already ordered two coffees so I was like "well, might as well sit down and drink it and then get out of here" (which in hindsight was pointless but seemed right at the time). And yes, I tried to pay him back for the coffee but he wouldn't take it. So I awkwardly made conversation while finishing my coffee as fast as I could, then basically told him "look, I don't want to waste your time since you were expecting someone else and I have a lot to do tonight anyway, so I'm going to head out" and we left. Was pretty embarrassed/stunned by the weirdness of the whole situation, but not too torn up about it because I wasn't really super attracted to him anyway. Just figured, well he wasn't interested in me but rather my friend and even if that's a bit of a blow to the ego I'm just gonna forget about it and move on. But THEN the next morning I get a text from him saying he had a great time getting to know me and asking if I'd want to hang out again and maybe go get margaritas, which confused the heck out of me since the awkward minutes we spent at the coffee shop the night before were clearly NOT fun for either of us and I figured he wasn't interested in me anyway seeing as he told me to my face he didn't mean to ask me out. But at that point I was pretty annoyed at him just for being dumb enough to get to this situation and didn't wanna deal with it anymore so I just didn't respond and that was that.
Now, the questions I have about all this are:
(1)what do y'all think was going through his mind/why in the world would he ask me out again given the circumstances? (he did seem interested when I met him at the party, trying several times to get me to stay longer and obviously asking for my number, but I figured he must've changed his mind about that later given how he reacted to me the next time...)
(2)Is it just me, or wasn't he kind of a jerk by blurting out that he thought he'd asked a different girl to coffee? To me it seems like it would have been nicer of him and less awkward for both of us if he had just gone with it and pretended nothing was amiss once he realized what had happened.
Honest/serious/decently nice replies appreciated. Sorry for the long post.
