Amy~

I've read all of your threads, (and to the best of my ability..remembered what I could...I'm sorta 'short term memory challenged'...lol).

I have to agree with Pom on this one.
There is absolutely no way that you can help someone who doesn't want it for themselves. Therefore, you are in a position where you have to rechannel your focus back onto yourself for now, which can be a very constructive thing. Such as seeking new ways for you to help him.

By redirecting your attention from him back onto you, (even if it means your attention is about him), it is still off of him, thus relieving any possible pressure that he may be experiencing. Not to mention that it will also provide you a better sense of constructive contribution to your situation. You will feel better for obtaining (even the least bit of) progress and he will feel less pressured, which will eventually offer him a sense of comfort...allowing him to relax a lil more.

Perhaps, what you can do with your redirected focus is to seek for him resources to which he can possibly obtain free medical care, as well as anything else that you can do for him.
Of course, discuss with him your intentions before hand and explain to him what your intentions entail.
Let him know that you are attempting a new strategy with hopes that good will come from it. Remember, that although this new strategy of yours is a diversion of your attention off of him, is actually a new tactic which is still primarily focused on him...but, just done with diplomacy.
(Sometimes, the best way to be in control of a situation is to create the illusion that we are not in control at all).

Also, allow him the opportunity to convey his opinion about your intentions. Communication is always the key. Ask him if there is anything he can think of that you can encompass in your strategy.
Anytime you offer the person their inclusion of opinion, (informing them that their's is equally important), then they are much more likely to be receptive of the new idea. They receive it as they, too, are included in making this new idea a reality, therefore will be far more open to the idea...even if they do not take part in making it happen, they are still included, nonetheless.

It may be a helpful part of your strategy, too, to offer him an alterior to the present. What I mean by that is, because of the fact that he is presently on the med, Suboxone and it seems to be a cause of some issues, perhaps if you were to do some research on the drug itself, print out your findings. Then research an alterior for that drug, print out those findings. And then, offer him the two results.
But try to time this in the overall scheme of your strategy...including any discoveries for free medical care, which should include any related information, (location, financial inclusions, doctors available, etc), include that with your printed results.
You can even offer to pick up the required forms for him to apply for free medical care, and schedule any appointments for him. And even offer your hand to hold, (if needed) to get him to go to these appointments.

Sometimes, when we actually have a visual for comparison it provides us the ability to see things in a different light. Especially considering that he may be suffering from depression.

I have to include, too, that I do not think that you are being selfish for not wanting to abandon him. It would seem to me that that would be just the contrary, depending on the situation and those involved, of course. But in your case, selfish would be the last thing that I would even think you are.
You love the man and are willing to support him to the best of your abilities. But remember, too, that because of the direction this matter is heading, you have reached a point where a new strategy must be applied.
But remember, too, ANY support you offer him is basically useless if he is unwilling.

If his libido is naturally low, there are ways of working that out. However, it sounds to me that there are other issues which take presedence over that at this time.
You may have stated the reason for this in previous posts, but may I ask, why was he taking the pain killers to begin with? Was it an acquired drug addiction without medical cause? He was prescribed Suboxone to remove his craving for the pain killers..that I understand, however....I'm wondering his reasons why he was on the pain killers to begin with. That right there may be a good starting point of his therapy, (once you find him the resource to obtain it).

I understand how frustrating this is for you, and for that I am so sorry.
The best you can do at this time though, is to reconstruct your strategy.
Even though you can lead this horse to water, fact is you simply cannot force him to drink. Therefore, you must find ways to make him more thirsty. And I think by attending to his medical issues foremost is the 'water in the well', so to speak.

I hope this has been helpful to you. If you needta talk more, feel free to pm me anytime. Be happy to offer what I can.

Take care. Keep us informed of your progress.
