Alistair Approval Rating Bugged(?)

I noticed that when I returned to Arl Eamons estate after finishing the "Captured!" quest I didnt get any romance options like "can I speak to you privately" with Alistair anymore and my dialogue was different from a guide I was reading on how to rule beside Alistair so I decided to look at his approval rating thinking it might have gone down but it was at 100 except that it no longer says "Love".. its now neutral. I loaded back my previous saves and it seemed to have started during the sacred ashes quest? is there any fix to this? because I'm already 78 hours in and I really would not like to start over only to have it happen again..
