So recently someone I'm very close to (or used to be) got engaged and is to be married in a couple of days, but of late (for the last few months) she's been very withdrawn, aloof, quiet, etc. She went out with me last night and got a little too drunk and kept trying to call her ex boyfriend, which I didn't let her do.
Her behavior is very worrying and I need to ask her if this wedding is what she wants but I'm honestly too afraid. I really can't.
What can be done in this case?
