My mum is getting really moody with me, i dont think she likes me anymore?

Well, my mums always being moody with me, i try my hardest to make her like me for a while, but nothing works. Tonight ive done all her chores for her, ive washed ive hoovered and mde the beds, hoping to get at lease a smile from her, nothing. not even a thanks. Its just me though, with her boyfriend shes all happy and joyfull, and they're always laughing, so i went down and asked if they wanted to watch a dvd so we'd all see it together, but she keept going mm ehh what do u want? and ignoring me. I just want her to take notice of me, its like a dont excist anymore. I dont think she wants me around when her boyfriend is in
