To give somenone
false hopes or to make someone believe her/him you are head over heels for that person
when you know for a fact
you don't give a damn about
it, but you keep it under wraps because you're either scared of hurting her/his feelings
or you don't wanna be alone. Sometimes that guy or girl winds up marrying someone else
(not always but happens)
has really become
a pain in the ass, but I don't wanna dump her. I'm so adapted to her company.
Sean: you're a fucking wimp, you should break up, you always
string girls along!!!
John: after I hit on Monica!
