We can support Chrom here better if he gives us an idea of how he needs support, so it's helpful to know his dilemna is at the moment. True we know of a past A, but if there are complications of that right now...we can support him better if we know a bit of why he's stressing currently.
I appreciate your attempt to support him off of this BB, and I'm sure he does too...and I'm sure it's helpful. However encouraging him to e-mail privately with you over the problem does in many ways disable us from shoring him up when he needs the support....it's difficult to support someone blindly. This is a support BB afterall.
Naturally it's Chromes choice....he may find it easier to confide in one person rather than many.
