Hi wifeno2
Well done though for reestablishing yourself in your own home, without him in it. Have you looked up on the Land Registry online what actual ‘rights’ he truly does have? Have you looked up what it says on the gov.uk site? It seems that as he is not joint owner, it would only give him rights to not sell the house from under him, but as you own it and he is not a resident there (change the locks asap!), he has no rights, but please check this for yourself, this was from a brief look at the wordings on those websites.
Your married status will mean that potentially in divorcing your house could be financially divided between you depending on circumstances, ensure that you get orders in place so that the world knows who he is and why you had to separate and get him out of your life, and make him stay out.
warmest wishes
