Making plans w/ new 'dates'

Making plans w/ new 'dates' superwife: So I made a 'boo boo' with the last one... kind of jumped the gun.  I thought things were going okay...but got slammed by making 'future plans' with a guy.

Not that I'm going to even broach it yet, but I have a wedding to attend on August 13th.  I RSVP'd yes, with a date (and added an addendum saying 'hopefully...I'll keep you posted).  It's my cousin, and I am in the bridal party.  So I'm sure I can let her know about a week before, when she gives the final count to the caterer.

So what is a safe time to ask someone if they'd like to attend with me?  I am involved with someone, only about a week since we met.  But to be practical, when do you hit someone with "I have a  wedding and need a date"?  It's 7 weeks away.  He has the type of job that involves weekends, so he may need to arrange for the day off. 

I just feel like I don't want to jump the gun, as I just did it recently with someone else.  I made plans 1 week in advance for something (that involved purchasing tickets) and he came up with a bunch of excuses.  We haven't spoken since. 

I was bold enough to ask this guy (the current one) if he was working july 4th (b/c basically I'm trying to decide if I should sign up to work).  He told me he was... I thought maybe if he wasn't we could do something.  I was even hesitant to do that, and it's less than 2 weeks away.
Re: Making plans w/ new 'dates' NO DATE: this can be a tough situation here's what I would do, ask anyway! if he flakes he ain' worth it, if he accepts great! or this option I call it the "spam technique" self explanatory but as the date get's closer start going down the list of possibles guaranteed results with this one! because if you ask enough guys murphy's law states that they will all accept then all you need to do is figure out which one you don't want to cancel on! ;D
Re: Making plans w/ new 'dates' superwife: Okay, so how do I cancel a 'wedding' with someone??  I do like your idea, but I'm nt a good liar  :-\
