Congratulations on your many successes Aristo, that's awesome.
I am particularly amazed at how you've begun giving back in such a big way. That's amazing and shows your dedication and commitment to your well being and that of others. Good on you.
In terms of dealing with the ex and the new gf, all good stuff too. It is hard to recognize the entanglements for what they are when we are immersed in a bad relationship, but sounds like you've seen them and have made your decision. In terms of the new gf, that's awesome that you were up front with her and honest. It is the only way to be man.
Again, congratulations to you on your many accomplishments ... your sobriety most of all.
Peace and good fortune, Levi
