Probably not. You sound jealous and are imagining things
Depends on what you mean by 'deals with'. Ex's can still be mates. I know plenty of people who are ex's and are still friends
If you still have feelings for your ex then let him/her know that, then you both decide if you still have a chance togther.
ask them
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 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.
if they are not threating you you are okay
ask him
only if you tell him
If she tells you.
if he has messages from her, or talks about her.
well if your ex still talks to u and u hate him then say that u have a boyfriend.
You don't, but if she is then that is her problem. It is your ex-girlfriend, you should have moved on.
