It's probably not fair to second guess what she wants either, I don't know Kirsty very well - well barely at all tbh - but if there's one thing I know about women it's that in a weeks time there's just no way of knowing what our hormones will tell us to do!
I should say something supportive here, but yep, you hit the nail on the head. This time try to learn that decisions made with alchohol are invariably bad, but more importantly, decisions that effect your entire future should not be made on a whim - acting impulsively is what I do, leave it to the professionals .
Now that's a different matter altogether. You've been with Kirsty what, 5 years is it now? And honestly what are you really bored of, the same person or the fact you're always broke so you settle into the routine of scraping through without really doing anything other than buy a micromeal a 4 pack and sit watching telly?
If I was your un-qualified doctor I would prescribe you one random frivillous thing every month - goto a concert or something other than hitting the gambling machines and getting wasted of a weekend. Because if there's one thing i've learned is you don't get bored of people - you get bored of what you share with any given person, and the way to fix that isn't to find new people but to find new things to share with the ones that you know - otherwise you just do the same with somebody else.
