My thinking is that this is really good news. Even if it doesn't last forever he is making an effort. I would love to see you have another good discussion with him. Maybe not specifically a R discussion, but a discussion on how you two feel about something of interest to both of you. Maybe the finances, maybe the kids, maybe the ships passing in the night routine at home, maybe sex. Something that shows you are interested in him and that home is not a place abandoned by both of you.
