It may be a good idea to sit down with him and explain exactly that: that you need social contact that does not include alcohol, and that you would like him to understand it and help you. You may also ask him what he feels about you socializing and that way you two can work out a pattern of social interaction that fulfills your need for social contact and does not threaten your H's feelings.
