My Gaslighting Husband - HELP I WANT TO LEAVE!

I could go into a lot of detail, but to sum up, my husband is a narcissist who has been emotionally, mentally and financially abusing me and I’ve been ignoring it until recently. He has done such a good job of gaslighting me that I have believed everything was my fault, thought I wanted an open marriage and agreed to not have a car or phone for myself (I’m a stay at home mom of a 6 month old girl).

He has refused to go to therapy with me and denies that any of this is possible. I have had several friends of his as well as friends of mine and family tell me he is toxic and that I need to do something about it.

How do I tell him I don’t love him anymore? How do I leave with my daughter? There’s no evidence of abuse so I imagine it will be difficult to leave the state with the baby and not have him report it as a kidnapping. I do have family to stay with and help watch the baby, as well as a few job offers.
