only if you tell him
it can be possible for an ex to still love you after a year of the break up...i know i still love my ex and its been about 2 years
if they are not threating you you are okay
if he has messages from her, or talks about her.
Well,
If you still think of your ex-boyfriend and talk about him that means you ain't over him. If you continue to hate your ex that means you still got feeling there.
They pretend to hate you, so no one "notices" that they still like you.
That you are still in love with them
You will know by the way you feel towards him and by the way he makes you feel.
you'll know it if you'r e still longing for him/her or if you're still hoping that you could still be together someday
tell him, its the only way he will ever know
she calls, mails you and ask you out again.
If you are not sure then you are probably just missing the sex, a natural reaction.
