I have been seeing a guy for a few weeks and it has gone extremely well. He recently said to me he doesn't want to date anyone else, I was his girl but we are not a couple yet. Today he has messaged me and seems to have fallen head over heels for me with lots of things he has said and he said 'now we are going steady'. Does that mean we are now in a relationship? I think he has reflected over the last few days.
