I do not think it's Tad's place to ask her to come back, i.e., she walked and if she wants back, she would have to earn his trust and respect and I don't see that happening any time soon.
I meant asking her to come back when he meditates. Our thoughts are very powerful and can be perceived by the spouse even if the spouse is 10,000 miles away. I keep reading about it and I am trying it myself, and it seems to be working. My wife has mental and physical problems right now due to midlife crisis and peri-menopause. Me sending her positive energy will speed up her healing process and because of Karma what I put out I will get back later: she is acting in a friendly way towards me and hopefully we can reconcile at some point.
