Well done for waking up in a positive, pro-active mood, and getting on with things. Great that you've made a solicitor's appointment, although it's a shame you can't get anything any sooner, and the fact that you've taken steps to protect YOUR money is also a very positive step forward.
Can I just ask though, have you asked him to move out and give you some thinking room? If so, what was his response? If you haven't asked, then I would do so, maybe suggest that he goes to stay with the friend he zipped off to rescue, so that you can both have time to think. He can plan his defence, and you can take the time to think things through properly (and go through all his paperwork, making sure to copy or take photographs of anything to do with his savings, income, etc.) I would also recommend that you take out any paperwork relating to your own income and savings, so he can't get his hands on it. Stash all of your own paperwork, together with passport, marriage certificate, your child's birth certificate, etc., in a locker at work if you have one, or ask your friend if she would take care of it until everything is sorted.
Be proud of yourself for taking the first steps toward taking control today, those of us who have been through divorce know it's not easy. I feel sure that once you've seen a solicitor, you will feel much stronger because you will then have a clear idea of how to deal with everything. Meanwhile, don't let the posters on here who don't believe you, get you down, the vast majority just want to help, and support you.
