Is there anybody who can clearly explain these to me?<br/><br/><b>If I were you, I wouldn't do that</b><br/><br/><b>If I were you, I won't do that.</b><br/><br/>Can both the sentences be acceptable? If so, would you tell me about what differences they have between them?<br/><br/><b>If she would be my friend, I will be happy.</b><br/><br/><b>If she is my friend, I will be happy.</b><br/><br/><b>If she will be my grilfriend, I will be happy.</b><br/><br/>I also wonder whether all of them are right or not. If so, please tell me what the differences are among them.<br/><br/>Thanks.
