Will the husband lose his wife if she remarries after his death?

according to authentic hadiths she will be with her last husband. does that mean her previous husband will lose her in jannah? what's the point of forming a relationship and taking the time to be bond then? aren't we supposed to find peace/comfort within our spouses according to the holy quran? So does the man just watch as his wife enters jannah with another man, knowing there's absolutely nothing he can do since he died?
