You don't need to get involved with anyone else right now. Now is the time to focus on you, to learn who you are again and how strong and content you really can be as an individual again. Getting involved with someone else before we've taken adequate time to heal and to grow is the mistake our spouses have made, and they are going to some day be in for more hurt and misery as a result of their foolishness -- we don't need to repeat their mistakes.
And if your spouse can't see how you've grown into the supremely desirable person you can be, then that will be her loss. If in time you do meet someone else, and you have had that time to learn to find peace and confidence in who you are, then you will have so much to offer that person -- and they will see that.
