Having love, support and encouragement does not in any way reduce the amount of energy, courage and commitment necessary to overcome addiction. The support, of the type you get here simply makes it less bleak; the support you get from your partner can also be a huge benefit. If you don't get this backing, then this does not make the situation hopeless, because the fight is essentially a solitary one. It is more about you fighting yourself and I don't really believe enlisting the help of a partner will make or break it.the OH is supportive to a point then doesn't seem to want to know. am i wrong in wanting him to be a bit more pro-active during my recovery??
You didn't make clear what the relationship was between you and your partner regarding drink. When you say he's only supportive 'to a point' suggests that he might have a troubled relationship with the drink himself. If that's so, then your intention to recover might be intimidating for him.
If your partner has no relationship with drink, his lukewarm response may be nothing more than not being initiated into the kind of struggles that nearly everyone on these forums face daily. It would be like asking a non smoker to sympathise with the nicotine withdrawals of someone giving up the weed. In that case, it might be asking too much of him to ask for more support than he can already give.
From my experience, I've always found it advisable never to have expectations of other people in most instances.
For myself, my partner never made a big song and dance about my drinking so it was hardly fair of me to expect her to cheer from the sidelines when I was battling to give it up. This was in no way discouraging. In fact I found it instructive that this this enforced, workaday reality confronted me. It was plain, unadorned and just what was needed.
I wish you all the best in your efforts.
