If you are living and working together and financially dependent, you two are NOT broken up.
You are merely stuck in a perpetual hell.
Love is only 11% of what makes it work, and it does this by making us WANT it to work. But that is what WHAT makes it work. As you have discovered.
Oh, I have been there. It is very sad. The best thing is to work out some way to detached, as quickly as possible. To stop living together, to stop working together, to separate the finances ... Only then can you start letting go, healing, and move on.
And you really DO need to stop saying "Still in love" ... as if that was relevant to the situation. All being "still in love" is doing now is making you miserable.
