I believe he does love her, but the fact that she was Logan's daughter made it soooo much easier. He has played his cards right with Logan so far, but Logan is a tricky customer and it may mean nothing in the long run. I don't think she really is interested in him sexually just based on what happened between them right before the wedding. She told him that she thought they would have an open marriage and he wasn't keen on that idea. She basically backed off on it, but later on the yacht, she was arranging a threesome with a woman who worked on the yacht. That didn't happen because Tom didn't want to do it. Maybe she married him because she thought he was safe and wouldn't make waves since he worked for her father. Just another form of control. Everyone in this family wants to think they are in control when you stop and think about it. They think they are and then they get shot down either by Logan or what is happening around them.
