The lover will talk with you , gossip about you and whenever she/he sees you , they might have fear .
When you're in love you feel so good because you know that someone loves you. And you know that you love someone so you're not lonely and desperate.
You know if someone loves you if you can trust them impeccably when they are out of your sight.
of course it is why go out with someone who doesn't know they love you? like really whats the point? you should want to date someone who really and truly loves you so yes its a bad thing!
If people could tell if someone loves them by the way they are looked at then life would be a whole lot easier. lol. Either way you never really know if someone loves you until you get to know them and spend time with them. So get to know this guy, spend time with him and in time you may find out if he loves you.
Ask them
As this someone will always like to call you and talk with you. The body language and the eyes can tell everything that someone loves you.
affection
you go to her house. meet her , tell her he loves you and she needs to find someone else
If someone loves you, they'll stutter or hesitate when they talk to you, they'll be protective of you, and they'd probably have a flirty look in their eyes
talk to Them
If someone loves you all they want to do is be around you and talk to you constantly. They will do anything to make you happy.
Jesus loves you, this I know. for the bible tells me so...
