The 800 pound gorilla isn't really there unless you let it be. If she wants to talk then be available but ler her come to you. Her silence is her problem. You playing and loving on your kids is how you create emotional connection without talking.
She will be attracted to you if you ignore the gorilla and keep being loving, interesting, fun, and confident.
