You did well to skip over the tone. I sometimes do that on forums.
ANYWHO, the issue here is that you're jeopardizing your rank to play with your presumably BEAUTIFUL and LOVELY lady, who apparently can't keep up with the action...let alone you. I think your best bet is to perhaps play Flex Queue when playing with her so you can really hash out what she needs to do to learn the game more. If you keep grinding it out LIKE THIS in ranked, you're gonna demote to Bronze V, and her to Plastic II, before you start seeing even scores. She must be struggling with core fundamentals and what-not to be this bad in Bronze III.
You two just gotta git gud. No way around it. Riot's way of balancing out your elo like you're asking is by giving you weaker opponents after you tank your mmr, and I don't think any of us, between me, you, and the presumably lovely lady, would want that. =/
