Ok thats I am going to be firm with you here. From a place of love.
A counsellor cannot tell you what to do - they are there to help guide you towards your own realisation. If their own opinion gets pushed across then they could get in trouble professionally. It was the same with my Health Visitor. I knew fine well that she though I should finish with FW and divorce him rather than constantly trying to fix things, because he was an abuser who wouldn't change, but she couldn't say that. Instead she said not very subtly! 'I know you'll do what's right for your kids'. 
And if a counsellor told you what to do, confirmed he's abusive and you should leave asap, it wouldn't matter, you still wouldn't take it on board because you haven't squared it with yourself yet. And that's more what the counselling is for, to help you see yourself that his behaviour has been beyond unacceptable, he has abused you and the children for years, and that you don't need anyone's permission to leave.
Lots of people on here, on this thread and your own threads, have given counsel and advice (all of the LTB variety), but until you believe you can, until you believe you are allowed, it won't matter. He won't ever, ever give you permission to leave him. He's already telling you why you can't leave him even after being served.
And this is the problem - you are still giving out all the signals of not LTB. You served divorce papers but then you went and spent the weekend at the other house with him, because he said you had to. Buying his dad a birthday present because he said you had to. Reading his mad emails because you feel you should and letting him get inside your head. Until you get some distance - some proper distance, ie not engaging with him at all - you are not going to get to that point of realising you can do this, that you don't need permission, that it's your choice.
So here's someone telling you what to do. (I know you are seeing the solicitor today, so hopefully they will have told you some of this too.)
- Stop engaging with him. Stop doing what he tells you to. Tell your friends you are divorcing him so you can't all socialise together. If they don't accept that, they are not friends.
- Stop reading his emails/texts. Filter all his emails into a separate folder and let them fester there. Get a new phone and a new number. All discussions through solicitors from now on.
- Call 101. Report his assault of you last night (dragging you back into the house). Tell them you already reported his harrasment of you by text but it wasn't dealt with properly. Admit to them (if it will make you feel better) that you also hit out at him in self-defence. Tell them he's made suicide threats and you are extremely scared of him. Ask if someone can go out and have a word with him, that you've had to have police involvement before because of his abuse. Don't take no for an answer.
- Seek a non-mol order. He's proved he's not going to leave you alone. Without it, you will need to deal with him turning up any time he likes.
He's not going to just leave you alone. You need to be strong enough to create a barrier in between the two of you - for your own safety, but also to give your head a chance to think straight about all this. Only then will you have any chance of realising that he's truly abusive and you need to be away from him.
Here endeth the post. I know you know all this already, but you minimise so much because you are so entrenched in it. You need evacuating out of the war zone - you need to be your own advocate, your own UN here.
