I do think Nick had been thinking about having sex with Adalind and she gave him an opening he wanted. Sex with her at the time didn't carry the emotional weight it would when being in an actual relationship with her but it wasn't meaningless either. Her being Kelly's mother was an excuse that made sense to him. Later in the season after he finds out she's a hexenbiest again, sleeping with Adalind was about her and not her being Kelly's mother. Nick as a grimm should have balked at the idea of having sex with a hexenbiest (especially her) but he didn't because his feelings for Adalind had evolved past her being Kelly's mom. She was finally her own person and not an appendage. Things continue to evolve between them when she finally confesses but she leaves him immediately after that and Nick loses his mind as a result. Nick's never been good at expressing himself. He talked a lot about getting Kelly back but what little he does express about Adalind reveals how deeply hurt he is by her leaving him and he only tells this to the people he's closest to, Monroe, Rosalee and Trubel. In S6 sex with Adalind now carries the appropriate deep emotional quotient that was missing the night before he left for Germany.
