DD (16) had a bf for almost a year. They were all loved up as teenagers are. A month ago he cheated on her at a party and, after lots of begging on his part and tears from them both, DD ended things.
DD has worked so hard to get herself back to "normal" again but he just won't let it go. He sent her flowers the week after it happened (DD binned them). He kept turning up on the doorstep begging to see her (turned away by us at DDs request). She blocked him on all social media but he keeps making new accounts and sending her Instagram messages saying how much he misses her and tagging her in stories. He turned up here again last night and left a bagful of her favourite drink, chocs and a teddy on the doorstep when we told him she didn't want to see him.
I told DD enough is enough and said I was going to message his mum and tell her if he doesn't stop them I'll be contacting the police. However DD is adamant she doesn't want that because it will just make it embarrassing at school. They're about to do their GCSEs and she will be going to college after the summer so they won't need to see each other after June. But I really can't see him stopping any time soon. DD had a panic attack when she realised it was him at the door last night.
DH thinks I shouldn't go against what DD wants but it's starting to border on stalking and I think he needs at least a warning to stop (we have told him ourselves to stop but clearly that's not working).
So AIBU to want to text his mum and follow through with the police if he does anything else?
