Second Question
Well I've done the chart:
Question: Will he leave her (especially if I am present)?
The universe has a way of making it's point. If you examine the attached chart you will find that Virgo rises and Pisces is on the Descendant. So your significator is Mercury (again) and his significator is Jupiter (again).
Mercury is in the eighth house and is combust, two very big accidental debilities, and is still in Pisces so has massive essential debility. Mercury is much weaker than before, but being in Pisces, is received by Jupiter, so you love him. (which we already knew)
He is Jupiter in the seventh. As before he has major essential dignity and now a lot of accidental dignity because he's angular in the seventh.
In this case, I've got to assign Venus to his wife, as it's still a Day chart (but the answer would still be the same if I had used the Moon). The same thing comes over in terms of what he is interested in and motivated by, Himself and Venus (which is now his wife). Whether he loves her or not, he is under her sway, as you are under her sway. You (Mercury) do not appear in his motivations/interests.
Mercury is still moving away from Jupiter, so your presence will not help. He is firmly in his own house and sign - he's not moving anywhere The Moon cannot help you as she's combust, though in the Seventh. If she were his wife's significator she would be at home with him, though if you wish to clutch at straws, she is on the eighth cusp, which might be interpreted as leaving home. She is however in his Sign, Pisces, and therefore she loves him (or at least the present arrangements) and the Moon rules his fifth House of children and romance. OK he might not love her but she controls the child (will she get custody as the mother, if it comes to a divorce, instigated by him throwing her out?)
Either way I look at the significator of his wife, I don't get a situation where he is going to leave her. He is dependent on her. You may well be right that this is drug induced and Jupiter in Pisces seems to symbolise that condition.
The good news, such as it is, is that Jupiter is stronger than either signifcator of his wife. He could throw her out if he chose to do so.
The bad news is that the chart does not indicate any willingness on his part to do that. Indeed if she is Venus, he wants her, (or the life style) and if she is the Moon, she has occupation of his house and controls his child. Nothing that you can do will change this situation - he himself must change if things will move in your direction.
One ray of hope is that only 3 degrees of Virgo is rising - it's perhaps too early to get an answer, or rather now is too early to expect him to break the bond. That does not rule out hope for the future but I repeat, he will have to change and change quite radically for that to happen.
I know this is not the answer you want to hear and I realise you may choose to try anyway. But you have to face the real possibility of going out there and finding he's in no condition to fight and your situation relative to him is extremely weak. Once again you need to consider your actions carefully.
Sorry to bring bad news but I think you expected that result, even if you hoped for something much better. Again I wish you the very best for the future and if I could change the result I would but that is what the chart tells me.
Edited to supply the right chart LOL
