Oh boo-hoo, your wife is exhausted from WORKING and RAISING YOUR CHILDREN and doesn't want to be your personal cuddle dispenser at night. What a shocker. Maybe instead of whining about your lack of physical affection, you could—idk—TAKE ON SOME OF THE PARENTING AND HOUSEHOLD LOAD so she isn't running on fumes by bedtime. Just a thought.

Oh wow, five whole months? You must be a record holder for suffering. Let's get real: an "excuse" that lasts half a year is called a REASON. She's not running a marathon of avoidance for fun; she's telling you the workload is unsustainable. Your math is simple: her exhaustion > your desire for cuddles. Fix the first part, and the second might follow. Or keep counting the months, see how that works out.
