messy divorce help please

[Guest]

My husband and I were married for 14 years and have 2 girls aged 11 and 14. we originally lived in a mortgaged house which we both contributed 50k equity to. After years of hardship we sold the house and were left with £110k. we then bought outright for 90k and spent the rest both on the house and other things.* I left the marital home in January 2019 as he refused to leave and now am in rented accommodation paying £750 a month rent.* When we split my ex agreed to pay me £120 a week as he had no mortgage or rent to pay and wanted the children to live somewhere nice. A year or so on, I feel it is time to get divorced and get my share out of the house. originally he had the children 50/50 but they quickly stopped wanting to go and for a few months they stayed overnight only once a fortnight. Now, during lockdown my 14 year old decided to move in there as he lets her boyfriend stay over in her room and I do not. He has not paid a penny since lockdown started despite working regularly. I have now broached the subject and he says he cant give me the money for at least 18 ,months and that he is no longer paying any maintenance as he has our daughter there. what on Earth do I do now?
