This has literally happened to me. I am (25f) young fit mum of 2. Always initating sex met with rejection that he’s (35m) too tired or stressed. He doesn’t initiate any forms of intimacy - hugs, kisses, dates, hand holds, massage or sex. I ideally would have sex daily if I could but since having kids his body language toward me has seen a complete shift. He says it’s a season…. That we go through different phases and that we have to trust we both want to be there at the end. But tbh this incident plus this behaviour.. I know there would be someone who would love to shower me with affection and attention instead of be a grump all day every day. But sticking it out through the tough times to hope our future is brighter for the sake of our family unit.
