My dear friend under the sign of leo or relationship from this sign i want to ask you, i hope you can answer me,im so curious about....

over a year with my leo mate we talk and we laugh together, and of course we fight sometime and together again... over the year we never used to talk what will happend for between us until one day i surprise that it came from his mouth that he ask me that if i want to marry him? my answer was so cool and said no... Because i thougth it was only a part of joke, then again he ask me you dont want to have child with me? when i heard that word i derict look at his face to say i like it that because i ask him before but he refuse me and he'd tell me dont mention it again... then again he'd tell same like asking too that why he want to build a house in my country? i dont know what will be my answer to him that time, so i said when i love you im not looking for good return im know his divorse for long time, he used to mention for me that he want a house in my counrty....
