Okay! So, I've heard of a lot of hints and have read lots of blogs on this, and have almost every time come up with the conclusion that it's all fake. So, I need real experienced hint's. Times when we get to know that he truly loves. Does anyone have any tips, that actually works?

He calls you, he stays with you, he is friendly with you, he is good with you, he is romantic with you, he is he with you, he accepts you, etc 

He calls you for no reason. He takes care of you. He is protective and is feels insecure when you talk to another guy. Listens to you even your stupid things. Loves to be around you. Text you for no reason. Makes you feel special.

And the most important, he tells you.

Ya, men aren't complicated we'll usually just tell her we like her  very primitive that way ya know eh

I think it means he likes you if he wants to be with you all the time, whether it's good time or bad times. 

Not necesary, you can be in love with somebody and don' t wanna stay all the time with him/her.

Only if he shows and say it
