No promises, but if it were me I would mask off anything you do NOT want adhesive on and spray 3M trim adhesive on it and gently put it back in place. Let it get tacky for a short while before you put it in place or you may have fingertip impressions if it is just plain wet with glue. I do NOT have experience with this exact problem, but fixed a friend's typical 80's GM headliner this way.

Mine is doing the same thing except it is not in the advanced stage that the OP's is. I've got new weatherstripping already and a new headliner on the way and I am going to remove, clean, and reseal the areas involved. The new weatherstripping already has a butyl type sealant pre-applied in key locations and is covered by a peel off tape. I will primarily use butyl tape (doesn't dry out) and I may augment that with some black silicone only if necessary. Any and all screws used need to have the threads sealed as well. New ones come with it already.

I would remove the old one and probably use a suitable brush-on type adhesive on the fiber type material, brushing it in between the "layers" you have now, then set a weighted item on it to compress it back to it's original thickness and dry. I'm thinking something like an Elmer's glue, or similar, etc. Elmer's starts out white and dries clear.That will at least "restore" and preserve the headliner as best as possible.
The real task is to stop water from getting to the headliner in the first place. Remove the trim moldings (2 per side) and the weatherstrip retainers (also 2 per side) and the weatherstrip, clean everything and reseal everywhere there was sealant before. Probably be a good idea to use a little extra sealant where you can, especially between the trim molding and the body, and then in between the trim molding and the weatherstrip retainers too. Prior to re-installing the weatherstrip itself, lay a continous bead of sealant down the middle of the weatherstrip retainer(s) and then insert the weatherstrip and get it tucked back into the channel that holds it.
