@PurpleLampShades
Take a breath, he's stressed, he's blaming you but look at what he's saying...he's got to fix it with her...
He isn't railing against you, he's worried about explaining to his girlfriend what's going on.
From experience, this may not appear to be a positive but it honestly is I promise you. He hasn't quite realised it yet but it's beginning to percolate through that he's not where he wants to be but he can't admit that to himself, let alone anyone else.
Stay strong, I know that's easier said than done (I've offered before but I'm offering again, DM me if you feel it would help you)
Take it as a big positive that he did contact you and accept that he's going to push back against you "interfering"
It's massively telling to me that he's texted you when she's quite possibly asleep, asked you not to message him back (see my earlier message today) and his primary concern now seems to be how to explain everything to her...
Keep going, you're doing the right thing, the best thing, and it will work out in the end. I honestly know it doesn't feel like it will ever happen but it will.
@stillvicarinatutu if you're around, do you have anything to add? Should @PurpleLampShades be contacting anyone else/ doing anything else that I (or PPs) haven't advised? Apologies for tagging you, I appreciate that you're working (family are Job) but you have been a consistent voice of reason and reassurance for OP 💐
