Well I won't say I've had "success" in getting back with a partner by doing the "no contact thing." In my bachelor years, after feeling like I'd been jilted it was always in my nature to do no contact at all whatsoever, even going to the point of turning my head and pretending I didn't see if we should happen to run into each other in public. This wasn't necessarily so much to let myself heal or because I thought it would possibly win them back but because of my wounded pride, coupled with a grudge that I'd hold against her for hurting me. Later in my life, as I began to develop a more healthy outlook, I'd find myself being the one to do the breaking up or adopting a "good riddance" attitude when she'd break up with me. At this point, I found that, although I'd continue the "no contact" thing, but now out of indifference rather than pride, these people had a way of trying to crawl back into my life as they'd call me many weeks or months after I'd last seen or spoken with them. It never resulted in a relationship being rekindled but I found it very interesting that, when I least expected it, there they'd be whether I wanted them in my life or not. So yes, I'm a firm believer that no contact works better than anything else.
