If you mean trust as in why are they not putting her in jail, I guess its because she just sacrificed her true love to save the town so they owe her for that at least.

Plus, its always useful to have a powerful sorceress on your side, in case you need to create a magic portal or something like that. Also, working together doesn't necessarily mean that they trust her. Just like Emma and Regina working with Gold doesn't mean they trust him.

Zelena was Roland's fake mother for quite some time. Probably, Roland's innocence awoke the maternal side in her, maybe that's one of the reasons why she wanted a baby.
