How do man reply to these questions?

Love is a big word, and relationship is complicated.. There's alot of types of relationship in this world.. I was wondering.. how guys treat their relationship.. And how do guys actually answer to this question under certain situation..

Situation one: You're currently single, and available.. you have totally no feelings for any girls and suddenly, there's a friend of urs came and say this to you:

1. I was missing you all night, do you miss me?
2. I love you, and i hope to be with you.
3. Do you love me?
4. How do you think of me?
5. I'm feeling horny, so you want to come to my house tonight?
6. I just feel like having sex with you, do you want to have sex with me too?

Situation two: You're currently having a girlfriend, and of course you're not avaiable..or maybe..u think you're still available..how would you answer or react to these:

1. I think i'm falling for you day by day
2. I really miss you so much that i couldnt control myself
3. When are you going to break up with ur gf? I'm waiting for u, do u know that?
4. I want you! I will make you love me for sure!
