My de facto partner and I split recently (after I discovered him cheating). We were together just over 2 years, and now he is threatening me, saying that he can take me for half what I own in property settlement, along with spousal maintenance as I supported him for a period of time while he was unemployed (I earn more than he does). We don't own property together (we still have a lease together which he is not paying me for since he moved out, he also owes me money for bills). He is currently employed, as am I. I have a trust fund from before we met (I inherited it), which takes the form of a company (which owns the property, and I am the Director). I have substantial debt (some of which I incurred while supporting him - he lost his job a couple of times and I supported him until he found work again). I haven't really bought anything substantial while we have been together. At the moment, he still has the keys to our rented property and I am feeling vulnerable as I have to travel for work. I am not sure what to do under Family Law. He has said he will continue to contribute a small amount to the rent and the bills he incurred while still living here, but I don't trust him.
