My partners ex

My current boyfriend of 1 and half year has this ex who is constantly trying to split us up. She tried last year on my birthday and then she tried again yesterday. She still has feelings for him 4 years later and we have blocked her on everything but she keeps making new social media and contacting us. My partner gas alreadg told her to leave him alone but she clearly doesn't get the messege. I dont know what else to do its getting to the point where i want to break up with him just so the hassle stops. 😩
