Your boyfriend tells you he wants to marry you and you only been together for about a month and he wants a kid is that called sprung?
Sprung is when he has an erection. Haha!
Your boyfriend has mentioned several times that you should ask him to marry you is that something you should do?
Generally it is the boyfriend that asks the girlfriend to marry him, but it is not uncommon for independent women to ask her boyfriend to marry her. However, in your case your boyfriend may be teasing you and if he is not then he is controlling and you should break up with him. When he tells you again to ask him to marry you tell him not to hold his breath because that's his job!
