Hello guys i have brought all DLC's for Skyrim now on PS3 so i built a house... i have had Lydia my companion throughout the Main quest and Dragon Born (not started Dawn Guard yet) i killed Parthurnax (sorry i know i spelt it wrong) and enlisted her into the Blades. I made her my house keeper thing when i built the house (can't remember what it's called) and i looked through the options and i still can't marry her... why and what have i done wrong?
