all you can do is wait and see how she is with you. unfortunately where alcohol is involved, people do things they wish they hadnt, their inhibitions are down & after what shes been through, she probably needed some fun & comfort.
however, she told you it was a no go for you 2 when she was sober, so all the cuddling etc could have just been her thinking, it was kind of a bit of kissing & cuddling for fun & comfort & that you knew that was all it was, because she told you.
she put a pretty big block on it, im assuming the religion thing is pretty big & cant be changed for both of you, so i wouldnt get your hopes up.
friendzone doesnt mean just a friend who didnt want to date you, it means someone who is using you & keeping you dangling by a thread & having you do things for them, like money, stuff, tasks etc, even to moan at about their boyfriend etc, and you accept it all, give gifts, be really sweet etc in the hopes of 1 day getting with them.
but theyre careful to keep you in the friendzone & on standby by always 'needing' you, praising you, but always puts a barrier to it going further.
this is actually not that common, most people dont use friends like that, but if thats what shes been doing to you & she keeps doing only that, to keep you hanging on then you need to move on.
remember though, shes just broke up etc so she needs time, so dont demand answers & try to make her be with you etc
