Any touch is an encouragement for Mulder; she might even know it already. This is a story he doesn't want to have to tell, but he knows he has to - she's owed that much, at least.

Mulder lets her go, waiting for her to lift her head and gesturing with his eyes toward the rest of the bed. He doesn't expect a complaint if he crawls under the covers, stretching out with a notion of pulling her into a clinging embrace. He'll tell her there, lying down with her head resting against his shoulder.
