While I applaud you for getting help for your depression, the fact is you waited until you hit rock bottom to do it (getting thrown out of your home). You recognized you had a problem, but you didn't respect her or yourself enough to get help for it. This obviously effected your relationship with your life and very likely could have damaged your relationship with your children.
The problem with waiting until you hit rock bottom is that there is often no going back, that often the damage has already been done.
That may be the case here. What you should do is concentrate on getting yourself together. Work with a therapist, keep on your medication, make yourself good. Make yourself YOU again. Concentrate on being a good father. And try to be a friend to your ex-wife. She may have fallen out of love with you based on who you became when depressed. Maybe she will love you again when she sees you trying hard to become the person she fell in love with originally. But there is no guarantee of that, so don't put all your eggs in that basket. Just make sure you are good and fit to be a good father and person.
I am sorry that this is probably not what you want to hear, but it is the best advice I can offer.
Good luck.
