Sure. Happens all the time. It can be uncomfortable and can even cause a serious problem, but it isn't unnatural.
Yes, it is possible but not recommended.
You could go out with someone else, or dont give up.
When someone sees God through someone else, that is called true love. When you would sacrifice yourself to someone else you are in love.
Yes, a man could have someone else.
forget him and find someone else
Romantic love is exclusive, if he loves someone else he cannot love you. If he claims to love you both then he is lying to both of you.
yes
because someone puts themselves in a situation in which they could loose everything, all for someone else.
If your guy is in love with someone else, cut your losses and move on. You can't make someone love you if they don't.
'I love you' and 'I'm in love with you' are two different meanings. Saying you love someone could mean as a friend or family, but saying you're in love with someone means exactly that, that you are in love with them that defeats love friend and family-wise. If he has said to you that he loves you but he is in love with someone else, then sorry, but he's saying he only wants you as a friend, and he has found his love in someone else. If you like him then I'm sorry :)
You cannot do much about that feeling. However you could have talks discussing and sorting that out.
yes
why cant she love you she have moved on Answer You either love someone or you don't. I don't know why someone can't love someone else. Do you mean she doesn't love you? No one can stop someone else from feeling love if that is what they feel so saying someone can't love you does not make sense to me.
