Don't feel like you owe him politeness. If you don't wish to reconnect, then be abrupt. This is to destroy any fantasy in his mind that he still has a chance with you. Leave no room for misunderstanding. Then if he persists after the warning, you have a stalker. I also wouldn't trust his innocent pretense for contacting you. Because you haven't communicated with him in so long, you really cannot know from his words alone what he has been up to.
leave it alone and dont contact him you awnsered your own question ,especially if it was abusive relationship
A tattoo? That would be enough to say no thanks. Move on, he is an ex for a reason
How does ur fiancé feel about this?....or how fo think he'll react then make ur move as to talk to the ex or not
Good luck and brace urself
You said abusive right? That answers it in my book. As for his motives, no idea.
