Can I marry a niners fan?

This seems like an dumb question… obviously love trumps all. I met a woman who has taken me by storm in the last two years. She captivates and motivates me and makes me happy like I’ve never believed I could be. The catch is she was born and raised in San Fran and her and her entire family are niners fans. As a proud 12 BY CHOICE (Im from south florida and never wanted to be a dolphins or buccs fan) I feel conflicted that our Sunday’s might forever be haunted by a looming sense of loyalty driven rivalry. She actually refuses to watch our head to head match ups with me at this point, but football will always be a part of both of our lives. We’re both terribly almost blindly competitive for no reason so what seems lighthearted and fun could get harsh quickly, we both know it’s just football duh…but still, am I betraying my 12’s ? Or can this be the start of something fun and beautiful for the both of us to enjoy and poke fun for the both of us? Obviously im going to marry the woman I love im really here to ask for the blessing of my 12’s. Thank you.

Side note: I plan for us to attend any and all play off match ups we have in the future even having to plan and pay possible nfc champion games the week of.
