1 1/2 months may not be enough time to have established an effective dose of medication and any other treatment plans. I was diagnosed 3 1/2 months ago and I’m still working with my doctor to get the dose right and establish effective strategies. It can take some time. There is no over-night cure.
My advice would be to determine whether he is merely taking advantage of you, or just needs more time to work out his treatment plan (that may mean he should allow you to talk with his doctor). If you can afford it, and he just needs more time, then it would be helpful to do so.
If he’s just having parties on your dime, that’s a different story.
