Is Sean really planning a future with Alliya past the 90 days?

I may be wrong but from the very first day Alliya arrived Sean seemed not 100% being there. When Alliya asked if marriage was in their future. Sean would not commit, I believe.he said he wanted to talk about it at a later date. So then she asked if now since they're together was their relationship just going to be between the two of them. Sean couldn't even commit to that. He was looking for a man, Douglas was a young man without alot of worldly influence, that's what Sean wanted. He isn't ready to be with just 1 sexual partner unless he could get everything he wanted. Alliya is pretty quiet about it all now. Will she just go back home in 90 days or lose all of what she was becoming & what she felt so natural was her true self. Sean sure doesn't seem like he was willing to change unless MAYBE he keeps Alliya & still keep an 'open' arrangement so he'll get his 'men' ??? Hmmm can't wait to see!
