does my fwb want to be more than friends?

so my FWB and I have been good friends for about three years and I asked him today if he would go with me to do some shopping. usually he'd just be like "sure I can help" but today he answered with "if that is your wish" so I asked what time and he said "what time do you wish?" I asked if a certain time would work and again he replied with " if that is your wish" am I just looking to much into it? I just keep thinking like princess bride and Wesley's as you wish thing...he has always said that he doesn't say I love you he shows it but eh just don't know!!
