Question

Right or wrong?
When I say "so you don't like me anymore"  anata wa watashi wa soreijou no sukikunai desu ka?

Answer

それじゃ、私のことはもう好きじゃないの？would sound right to me. (あなたはcan be omitted in this case.) 
 Anta is rarely used unless you're furious with someone and want to disrespect him/her.

Answer

それで、私のことはもう好きじゃないですか？（sorede, watashi no koto wa mou suki janai desuka?）
