Since this is your/her first year dealing with this, is there any way you can trade a Sunday or two to show her some attention?
I get relationship triggers when football season ramps up because Crazz historically removed himself from our relationship and became an imaginary 49er. I grew up loving football and watching it with my dad, but my husband took it to a whole other, detached and distant level.
Culturally, I get that sports are a big deal for a lot of people. The thing is, in the wake of infidelity, the BS sometimes feels like anything that takes the attention off of them is an "AP" so to speak.
It would be a HUGE gesture to make a plan for the family some Sunday and say, "You're more important than what's on TV. I can prove it."
I'm not saying give it up forever, or even all season. Just do the work to prove that she comes before all else. Does that make sense? Actions speak much louder than assurances. WS's are constantly asking how they can prove their devotion - this is your ticket.
