I don't think we're going to get along because we think so differently.
この場合次のように言うのはどうでしょうか?
ーMaybe we shouldn't see each other anymore.
「私たち、もう会わない方がいいかもしれない」
ーI don't think we're going to get along because we think so differently.
「私たちは考え方が全く違うから、うまくいかないと思う」
to get along で「仲良くやっていく・折り合っていく」
ご参考まで!
