Your wife and your situation are unique and it's impossible to predict whether she'll be one to return or to stay gone for good. I always say, as long as there's breath in your bodies there's a chance she'll try to return eventually. That may be even after you've both moved on with other people.
As far as friends and family, be careful with their advice. They cannot guide you objectively. Likely the majority want to see you two back together, so that want will cause them to give you advice with that goal in mind. It's better if you don't even discuss it with friends and family. That's what IC is for. Friends and family should be supporting you emotionally, spending time with you to get your mind off of things. Not giving you advice. You can help them by saying "I don't want to talk about it" anytime the subject comes up.
