Get a divorce. This should have happened 3 years ago. I don't believe in separation in marriages. It just gets him used to not having each other around. Why give him all the power in this? If your unhappy he doesn't let you in or with him in general you can end this too.

... He is going through some kind of depression and won't let me in...
With being 'Married for 10 years in October,' it sounds like hubby has by passed the seven year itch. However, Now it has taken its toll on him, he may be going through a Relationship Rut and has the baby blues.
This may be not all he is going through here, dear, there could be more than meets the eye than you even know. He could be actually suffering in silence with even Depression that has led to Real mental issues.
Give This a last try. Ask him if you both need to seek help for him in some way. If he pushes You away and refuses to go or just 'Refuses' to get help in this marriage, then tell him that while he took '3 days to decide,' you have been doing some soul searching of your own and want to take A... Long break with No contact now.
See if this First helps in this relationship. Sometimes absence makes the heart grow fonder. And along the love lines if it doesn't help, then maybe it is time to take more serious matters into your hands and seek other 'Help' for termination.
The 'Different situation' that you are In is Not healthy and with almost '10 years in October,' a girl can get real old waiting for a husband to come around, especially one with Issues.
Good luck, my blessings for you please to stay strong. xx
