My fiance and I have recieved over 1000 text messages in the last few months from his ex., anywhere from 10-15 daily and with out response from us. She contacts his family members also. The messages come back to back and the more we don't respond the more she sends. it's getting out of had and with the work my fiance does it can tend to be very distracting. The only reason he will not change the phone # is because he wants to keep the line open for his children to contact him.
