How do I leave?

Hey all. I want to leave my boyfriend. Thing is, we have two kids together and I am not earning enough for a bond and 2 weeks rent. To those who have left their partners; how did you go about it? I have no one I can move in with and I do not talk to parents- long story and no, I will not consider having a reunion with them.

I'm in Australia if this helps. We have this house but he pays the mortgage- it's technically his house and I have no interest in taking it from him.

Also, I hate having any sort of confrontation with him but how do I tell him I want to leave? There is no body else, which he will accuse me Of, and he doesn't get violent but I'm so over the verbal abuse I cop. Is it worth getting a lawyer involved as well?

I never thought I would be writing this post but I'm so done. Sick of trying, sick of being disrepected, being accused I've things I haven't done, sick of being told I'm not worth anything. My kids need their mum to be happy again.

Edit #1- he has never been interested in therapy. I tried years ago and he told me no straight up as he doesn't believe in it.
