You're not admitting defeat! You're realising the true extent of his behaviour and emotional abuse towards you. And therefore you are taking positive steps to remove yourself and your beautiful dd from this destructive relationship.
That is positive. It's a step forward. It's a step closer to you and dd being happy.
You can see all of this yourself and are making all of your own decisions and choices. Our posts on here may confirm your thoughts, or they may be the total opposite of what you want/decide to do - but that's ok, because you are strong enough to deal with all of this and make your own choices. We just want to support you in whatever you decide.
Can you make a small step by speaking to the CAB to find out your rights, entitlement to benefits, entitlement to maintenance, how you would split assets, entitlement to the house... savings etc...
Begin to arm yourself with the knowledge you need. Photocopy documents and bank statements. You may or may not ever use it. But it's a good step in the right direction.
It's hard to make a choice when it's a potential step into the complete unknown. But sort out the financial and accomodation side and everything else will fall into place xx
