Home Ownership Deduction

Hello,

I have a 1098 from my home mortgage. This property was purchased by my significant other and I. Although the 1098, loan, mortgage, etc only has my name and social on it besides the deed to the home. The deed has my significant others name along with mine. She couldn't be on the loan due to financial circumstances however each month we split the mortgage evenly. I still pay everything she just sends me money. Are we able to split claiming half the 1098 on each of our returns? Or should I just claim the whole 1098 on my tax return and she cant claim anything? Just want to do it right.

Thanks!

Thanks
