What sorts of non-lovemaking activities and such did your characters bond over? Shepherding the most wayward children/teenagers at Xavier's school. Long chats around the dinner table. Forge's outdoor Native time. Saving each other from disaster.
What sorts of non-lovemaking activities do they do together? Put out everyone else's fires. Unwinding and relaxing with each other. Putting boots into the correct asses - educationally.
What kinds of things do they talk about when they're together? Anything Xavier's school related. Their feelings (he doesn't do that with anyone else). Share interest in the outdoors and being left alone.
What dreams and goals do they share? Being warm and safe with the people in their family. Being left alone. Not having to fight anymore - a better life for mutants.
What dreams and goals do they have that they do not share? Logan would retire to the woods and a log cabin, he doubts the cyberpath agrees.
How many children does each partner want? Have they discussed this? If not, why? Logan hadn't planned on having children because mutants with his mutation are generally shit magnets. Yes, over many late nights around the dinner table.
What other plans do they have for the future? Which ones have they discussed? Why and/or why not? Logan plans to do whatever he can to protect his family, they discussed this at length.
What are the most difficult situations they have faced together so far? How did they overcome them? Their meeting was a difficult situation, several attacks on the X-Men and the mansion, his incarceration. Together, that's how.
What are some of their best memories together so far that have nothing to do with sex or the development of the relationship? When Logan would tag along on the Native adventures.
What things do they do that get on each others' nerves? Eva has a habit of surprising him more than he's accustom to. She also makes him care about things he'd rather not.
What little personal quirks and unusual tastes do each have that the other is aware of? How did they learn about them? Logan knows Eva had a tendency to cyberpathically shop, read others' messages, drink too much wine, go days without sleep, and be fiercly competitive. He learned this by spending years around her. She has probably understood by now that he's very simple by nature, but moody as hell.
What views do your characters disagree on? How do they reconcile their differences in opinions? Logan has a more isolationist view on things, Eva's more outgoing. Eva: "I'mma push him."

What is the biggest potential threat to their relationship? What is the most likely threat? Outside forces.
What would each partner be willing to change about themselves for the other? What wouldn't they be willing to change for each other? Logan would agree to all of the superficial changes - clothes, living environment, cigars, beer drinking, etc. The values and ideals that make up his character as a person he would not change, and knows Eva would never ask him to.
