fable 3 ellis wont love

ive been having sex with ellis and hugging her and kissing her but she stays happy with me and doesnt love me. Is there a way to make her love me

Check your quest log. Oftentimes, a character will ask you to do a quest for them or to take them on a date before they "love" you.

Maybe she's not interested in a long term relationship and is using you as a boy-toy:)
