Argo, I fear that late entry into the military, coupled with the present conditions in the Forces, and having once been commissioned, and having high status and qualifications as a specialist professional, will likely lead to you becoming increasingly frustrated. You will be treated very much as a new boy, also being led(?) by very young officers who will keep you at arms length because they don't know how to handle you, your previous experience or your age.
I remember an AEO from the Nimrod fleet (AEOp, got a commission) who in his mid thirties went for an ATPL. He's been commercial flying for 6 or 7 years now, and when I saw him recently he was wearing a permanent grin. He loves it - head and shoulders above what he was doing in the military.
After a lifetime career as a mil pilot, my advice to you is that, in view of your circumstances, I would go commercial.
