well for me, i knew when they started to seem a little more distant, less communication between the two and argued a lot. it's simple to know, if you think that's whats going on, it probably is and you should take it in your own hands and try to see what you can do before it ends badly. try suggesting you want to do something on your own, without them, and see the reaction. hint about splitting up and ask what they would feel about something like that. base your actions on their actions. hope this is helpful.
Everybody loves somebody sometimes
It can certainly happen, especially when you're young..I think what you feel is not love..Thats only attraction to the person you doesnt know.......
== ==
You got to know that he doesnt like her or him
When you know in your heart that it's meant to be , even when your mind says no and your heart says dive in with both feet and and also when your gut says so too. That's when you know when your deeply in love with somebody ;) I think you know when your deeply in love with somebody is when you care alot about them and you would do anything for them. to know if your deeply in love is when you want to be with them even as you progress more in life. Love is a big thing to have for that speacial somebody, but if you love them deeply, then you will know that you will want them in your life and not have to let them go.
Simplest way is to ask them.
No one knows
Well i will say froget about him/her cause your just hurting your self it always happens to people but they move on:]
then you're a terrible person.
you can love doesnt have an age well theres and age for marrige you have to be at least 16 to get married.
He probably loves you..or is seriously infatuated with you.
When the one you love, already loves somebody else.
