Trying to cut contact with another woman with whom I’ve had an affair for a few months. After seeing her for a while I decided I didn’t want to leave my stable relationship and tried to cut contact. But it seems she’s obsessed with me, if I block her on instant messenger she will call 100 times per day using an unknown number. She threatens: to kill herself, to call my partner ruin my relationship, to visit my work and see me. So I have to unblock her, and then every so often the pressure builds up and we meet again. I don’t want her in my life anymore, but I don’t know how to make her lose interest in me, I’ve tried being an asshole, I tried being a friend and encouraging her to date other guys–which she did. But she keeps dumping them and coming back to me.
