What can I do to make my ex move on? - YOU can't. You cant make anyone move on, only your ex can decide that
So It’s been a year since I dated my ex - ok
but she still tries to flirt and even gets mad at me for what I say - why are you communicating with her? She is your ex? To her, any communication means there is a chance still with you.
I’m not her boyfriend anymore, so why can’t she see that? - because she doesn't want to see that and you communicating with her (however, briefly or rudely) gives her hope.
I’m my own person, so it pisses me off because she starts drama for the dumbest things - so she has issues then
I honestly feel like telling her to **** off and leave me alone? - well why don't you ? She is an ex and most adults are NOT friends with ex's unless kids are involved. Are kids involved ? If not, cut her out of your life
But I’m still a nice person to not say it - its not a case of 'being nice' or not nice. She is an ex. She is part of your PAST, not your present or future. You don't need to be 'not nice' to her. Tell her you enjoyed what you had, but its over. Tell her that you will no longer be in communication with her and then you need to ignore any further messages from her.
What’s more, she’s a cheater, so I don’t know why she’s still crazy about me? - because she has issues
We didn’t even have sex, so what’s there to miss? - Exactly
What would you do if you were me? - you need to cut her out of your life.. If you see her in public - be polite, say hello and no more - do NOT engage her in conversation. There is no need to be rude to her.. Just walk away if she tries to continue the conversation.
You also sound a little bitter - you have one brief relationship with a woman you didn't even have s&x with and yet you have denounced ALL women. Everyone out there has had failed relationships and been messed around and hurt.. you learn from it and get over it and move on...do NOT let this woman determine your entire future life
