It is unclear which of the two he will miss, the meetings or the wedding.
What does this mean:
I'm trying to schedule my meetings around the wedding but it would be cutting it too close.
Does it mean that he's trying to make the wedding or miss it?
He's trying to say that he wants to schedule his meetings so that he can still attend his friend's wedding.
We usually use "cutting it fine" in BrE when we're suggesting that two things will be so close together time-wise that one might be missed.
I'm hoping to organise my meetings so I can still go to my friend's wedding but I'll be cutting it fine.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
You are right. He didn't make it.
