OK, so the stalker option is out (which is right) and now the only option is going to the same bar to see if he's there, which is fair enough.
But the problem now is that even if he's there, will he approach you? I think you'll have to approach him and chat him up this time, and even then it might not work out.
Here's why:
I assume he's tried texting/calling you at this stage and has come to the conclusion that the phone number is a dud.
I think we need to talk about how false was the number? Is it a totally random number that could be someone elses, is which case his texts are getting through but he's getting no reply. Or is it so false that he's not even getting a delivery report. Or is it one digit off your number, in which case you MIGHT be able to claim memory loss. Or the best option: is it an old number you had before? Maybe you can say you lost your phone......
You know what, I'm like a dog chasing my tail! I can't see a reasonable excuse out of this because if you lost your phone, then why did you get a new number when it's always so much handier to just get your old number again. Especially if a romantic interest is going to be texting you!
Anyway, back to the gist of my post...he's 30 years of age, he'll have looked at every option as to why his texts haven't been delivered or replied to or whatever the case is, and will have copped what has happened.
I'm a 30 year old and looking at it from his point of view, he went up and put his balls on the line to chat up a random girl across the bar he thought was nice and by the time of your parting the next day, he will have thought he was a pretty fucking ace guy for pulling all the right moves and hitting it off with a nice girl.
But as the week went on, he would've realised that you gave him the wrong number, which basically meant you wrote him off straight away. That's a blow to his ego. So you'll have to do the approaching this time.
You say you hit it off that night and the next day and that may stand to you if you spot him again. He might shrug off the write off, after you have approached him, knowing that you had a connection and that you feel differently about him now than when you gave the false number.
But you have to be ready for the other option which is that he thinks you're screwing him around.
At 30 years of age, most fellas will be able to tell you of how they thought they were onto a good thing, then the girl disappeared off the radar, no word from her despite the connection made.
It's the Bermuda Triangle of dating, so much so that we don't give it a second thought anymore. We assume she has no interest, that she's just boosting her ego after a recent break up or she's a prick-teaser or something, write off the lovely encounter and ignore her if we see her cause we couldn't be bothered with a head-wrecker!
So even approaching him in this case could earn you a cold response!
Looks like being honest about what you did is the thing to do if you spot him and go over. He has doubts in his mind about you now so you have to dispel them for him, because if a relationship kicks off, those doubts about this unacknowledged lie will fester.
Here's to this weekend then!
