Start cooking!! Show him how GREAT veggie food is and cook things where they don't even realize there's no meat.
My fiancee and I have been together almost two years. I was veg when we met so that made things a bit easier but we have an almost meat free household. I too make an exception for lunch meat so that he can bring his lunch to work. That's the only meat we keep in the house and it's in a plastic deli bag which is put in the "meat" tupperware container and stored in one of the drawers in the fridge.
I cook most of our meals and have some GREAT recipes if you're interested. In fact, tonight I FINALLY made a really good No-Beef Stew. Jack (fiancee) said the consistency and taste was PERFECT and I loved it. I search online and here on VB
for familiar, homestyle, omni approved recipes. Once I try 'em out if it's something we both like I add it to our "favorites" and start incorporating it into our meals.
Like I said I was already veg when we met so we had an understanding from the beginning. Others here have given good advice but you need to remember that you are the one that has changed, not your husband. As much as we hope and wish they will
"see the light" and change their ways we need to accept that may never happen and you have to remember that it's not only your house but his as well and doing something like trying to forbid meat may not go over very well. That being said talk to him about the way you're feeling and see if he is open to picking up his own meat and/or making any other compromises. He sounds like a supportive, loving husband and if you can gently voice your feelings without attacking him I'm sure you can work it out.
In my opinion cooking great meals is the easiest way to persuade anyone to eat vegetarian...even if it's only at home. If you're interested in any recipes please PM me. I'd be glad to share mine and my fiancee's favorites.
