If she blows up, tell her you can't help yourself. She's so beautiful and you really like her. Some degree of AFCish stuff is okay for conservative girls. You don't "game" them as hard as regular girls. That literally scares them.
Though this is an explanation that borders on an apology, do NOT say "I'm sorry". Tell her that you really like her, but you feel like you're ready to start kissing. Don't make her decide right then, because she's emotional and not in a good way. Next time you see her, get her in a good mood and then bring the topic up. If she says she's okay with you progressing there, congrats
If she says she's "not ready" it means that she basically just likes you as a friend and isn't really attracted to you. You can't force attraction, so at that point, you'll have to cut the relationship.In any event, there is nothing you can do at this point to "make it work". You're either in a place where she wants to do this with you, or you never will be. You can't convince her to be attracted to you. This is really just a way to find out where things stand. It's not a gamble, just a way of gaining understanding.
Do tell us how things go
