He always says he could easily be vegetarian and that we should eat far less meat. He also says he wants to eat less generally. (He is relatively thin, but wants to stay thin.)
At the moment I do most of the shopping - he's over 70 - but we take turns to cook.
If I put lunch on the table - pitta bread, hummus, olives, maybe some leftovers, fruit, cold meat salami - and often there's a lot to choose from but if I haven't put out any cheese, he will always want cheese as well.
I nearly always cook vegetarian food when it's my turn. At which point he either says, 'I fancy something meaty tomorrow'. Or 'I fancy something fishy tomorrow.'
Which is sort of okay - if inconsistent with the stated wish to be vegetarian. I feel that it's all talk with him and rarely translates into action. Fish in particular is something he always wants to eat in larger quantities.
But I can't help feeling a bit fed up when I've found he's just defrosted a packet of 4 cod fillets for tonight - for the two of us. In my head that was two meals worth of fish..
Though I go on about it less I really do want to be more vegetarian. So I reckon the answer is that for everytime he defrosts a double portion of fish, I'm going to make the next two meals I cook vegetarian/vegan.
I don't feel I can change him, only my response to what he does.
