ex-spouse does not automatically terminate' spousal support; it shifts the burden to the support recipient to show extant extraordinary circumstances that justify continuing the support. In re Marriage of Shima, 360 N.W.2d 827, 828 (Iowa 1985). Melissa did not make any showing that would justify continued receipt of alimony. See In re Marriage of Johnson, 781 N.W.2d 553, 558 (Iowa 2010) (explaining the failure to show any extraordinary circumstances warrants termination of spousal support after remarriage). Accordingly, Melissa’s spousal support was appropriately terminated. Melissa’s remarriage and the consequent loss of spousal support alone may not be a substantial change in circumstances justifying modification of child support. See Mears v. Mears, 213 N.W.2d 511, 516 (Iowa 1973) (<HOLDING>). But they are clearly factors the court shall
