What I would do is tell him to buy a big size and then you can have it made to fit. God what are men like
It took my OH years to actually come round to the idea with no persuasion from me, he just thought one day. "what the hell am I playing at, we own a house together, we love one another and we want to be together" Even though we owned the house together he hadn't moved in completely, on the day he did I had balloons waiting for him with "Welcome Home" written on them, when I got home the balloons had been moved which confused me, I went searching round the house for him and the balloons and he had moved them to the top of the stairs and written "Will you marry me?" He was hiding behind the door of the bedroom as he was scared of my response. That was 3 years ago, we're still not married!! When I've mentioned that our DD has a different surname to me he has suggested I change my name by depole!
I'm not in a massive rush to get married though, but I do know I don't want to have to many wrinkles when we get round to it, and I'll be 34 this weekend!
So the wrinkles are increasing by the month!
