How long should you wait to know if he is real or not


The thought of writing about this topic came to me when I was having a discussion with some of my female friends. It all started when one of us was telling was about how this guy she met at uni stalks her and  that she got frustrated that she had to tell her boyfriend about the guy. The boyfriend took it upon himself to protect his girl and she told us that he went to the guy and told him to leave his girl alone, after this the stalker guy stopped talking to her. As we were all laughing and making the most of the time, my friend asked a question that could this guy be genuinely in love with her? Me and my other friends were a bit confused by this question and we were just sat there looking at each other's faces, we had no answer to her question no one was sure if the really liked or loved her or was just telling her to get into her pants.

Then on my own I was thinking is it possible for a guy you met just over 3months be claiming love already?  She met the guy at the start of uni in September and they have been friends since then. After we went for Christmas break in December and came back January, this guy came to her and told her he loved her. My friend said she was shocked and she felt like slapping him because she thought he just wanted to take advantage of the fact that they are friends. Then the next day, I said to my friend "you know I thought about this and I think he might actually really like you" she was like what do I mean, I said he could really like you and could have been thinking about you through out the holiday but may be he just interpreted his feelings wrong.She looked at me like I was crazy then I explained to her I know love is not something you should just say out and that I know it takes time for someone of the opposite sex to actually say to you I love you because even 2people dating sometimes do not profess their love for each other until after like 3months into the relationship so obviously the guy could have really liked her and interpreted his feelings in a wrong way or he could just have said it in other to get into her pants.

That is my own view on an issue like this but when and how to you actually know when a guy is real? How are these girls supposed to know if he is not just lieing to get her on his bed. I think its really hard and its like a risk because we all know guys can lie. Is it crazy for a guy to say he loves you when he is just your friend and not even with you?, Assuming you guys are now together how long should it take for him to start professing his love? or is just something in you that makes you know? is it different for each person? are there some things you should see in your partner that will make you know if he or she is now in love with you or not?

I need answers to these questions, need you guys to share your own views about what you think is right, what attributes will make you as a person say yes this is love or not?
