Here she answered it herself:
She doesn't mind interacting with her in a group setting as Emi was invited to both Girl's Trips and Shit Camp, and Maya invited her for the cancelled 2022 Halloween event, but she probably feels too awkward to invite her for a solo collab.
She never hinted that, she literally said "replace in every way but romantic", and from what I gather Miz and Emi didn't actually start dating until January based on him hooking up with other girls prior to that.
They did not break up in July, they broke up in September a few days prior to the announcement. Their relationship was rocky for the past few months but they were still together. Just cause Simply's gf said so doesn't mean she was correct.

She wasn't dismissive of her stalker situation, she just pointed out that Emi didn't move to Miz's house, the place with a doxxed address and no security to avoid a stalker, while she could have moved to a secure apartment complex anywhere else.
