Well GH31, I was wondering what happened to you. There was a time to think about life without your wife, but I think that window closed with the announcement of her pregnancy. I'd say that now you need to make a reasonable shot at this.
With the exception of not hearing "I love you", how is your relationship any different than any other marriage? Are you otherwise behaving like a marriage couple? If so, then just go with what you have. Work on your end to play to her love language. Don't get into a situation where she even has to express that she is working on loving you. No one wants to hear that. You know that you don't need her to survive; that you'll be fine if worse comes to worse. So, don't worry about what she's doing at the moment. If it turns out your betrayed again, you can handle it at that time. For the moment, just relax in the relationship and work to strengthen it daily.
