Hello Natalie, it's so difficult to live in a love-less and a physical marriage, because you don't know what's going to happen next and that's what is so frightening.
There are a range of different antidepressants (AD) as I tried about half a dozen or more before the doctor found the most suitable one, so if I can suggest, if one doesn't work for various reasons, then ask your doctor to cconsider a change.
There are several options for you to move out, firstly if you are receiing any Centrelink payment, then you are entitled to get the bond money and two weeks rent from them, which you pay off over a period of time,, plus you can get 'rent assistance'.
Op shops can provide you with furniture or you can lease the most important, paying a small amount each month or may be others may help you out.
If you are paying off the house/flat then he an either buy your share or it's sold, because living like you are is not very pleasant at all and not safe for you.
You mustn't forget that he too, may want the marriage to end so that both of you can move on.
Do you have anyone who can act on your behalf and discuss this with your husband or perhaps this may not be wise when you are still living with him as you are unsure of his reaction, so this may be best if you can momentarily live with someone else.
If you decide to move out while he is at work or away, then choose what you want to take and this can be stored in a storage unit at a cheap price.
There are other options but would like to hear back from first.
