Glad you have taken legal advise @Waffletots
I'm sure they told you that as joint owners he can come back into the house /live there
You can't lock him out or change the locks / he has rights
Those who say lock him out etx - that is illegal and he can make trouble for you if you go down that route
Equally As much as you don't want him there he won't be able to stay in hotels forever - if that's where he is staying
Assume he isn't back with ow - she has prob dumped him due to his lying /we aren't getting on/never have sex etx
Obv you being heavily preg contradicts that
So you will need to talk to him. With someone else present
Guessing bottom line is that you sell the house and find somewhere smaller if he won't leave
Job depending he prob won't be able to pay the mortgage on joint home and rent /buy for his self
I'm still in shock that he hasn't even asked about your dd or how you /baby are
As I said previously you have the female mn on your side
And yes you can report your post to mn and ask for it to be moved to a diff section whether relationships or where you want @Waffletots
