I remember a girlfriend and I having a pretty heated argument over alcohol. I thought it was ok, she wanted no part of it and did not see thebpoint of drinking unless it was to get,drunk, which we both do not do. I, however thoght that drinking could be enjoyed, done in moderation, and was just fine.
Simply, she was raised to not associate with alcohol, for good reasons, and I grew up watching my dad have an occasional beer and never thought anything of it.
So, we were very conflicted. I actually just dropped the argument for a while. But, everynow and then I'd mention it, and talk a little about enjoying responsibly. Slowly, she came around to see my opinion, and why I held it. At the core was trust that she had for me, and my decisions, and also my respect for her feelings, opinions, and worries.
Now that girfriend is my wife, we are very happy, and she surprises me with woodford reserve bourbon, or some nice beers from time to time.
So, there's trust in eachother and eachothers motives and intentions, respect for differing opinions, understanding, willingness to change, and patience from both sides.
