How do I seem supprised?

My b/f has told me three times in the past two months that he is going to get engaged to me on my birthday which is at the end of this month the last time he told me he also asked me my ring size so he could buy me an engagement ring. When my mother asked him when she talked to him last night what he was planning for my birthday he told her what he was planning, but he never told her he told me. Now he tells her that he wants me to be really supprised on my birthday, but since I already know it is going to be a little hard for me to be totally supprised, but I want to try. How can I appear totally supprised even if I\'m not really so I won\'t hurt his feelings?

Lol If he wanted you to be 100% surprised he probably should not have told you and though you know he is going to ask, if you don't know how, that will be the surprise.

Ahmm,,just show what you really feel,,
it will be nicer than forcing ur self to be surpriced

^^ I guess you are right. I'll deff. ask him to stop reminding me all the time like he did again last night. I think the thing is that he is just so happy that he can't help himself and I can totally understand that. I mean it will be special no matter how he does it, but I just want to seem supper supprised because I just think that would make the moment more special for him even though I do already know about it. And my mother told me this morning before I left the house for school that she is taking him some place this Wendsday so he can pick me out my ring. I didn't mind that she told me as long as she doesn't tell me where the ring came from, what it looks like or how much it costed...lol
