My boyfriend has this major stalker who is completely creeping me out now! Sending me abuse and telling me she has slept with him then messaging him begging for sex asking why he hasn't given into her yet. She's saying stuff like she physically hates me for not stepping aside and letting her sleep with him, even telling him to ditch me because she thinks he'll be happier with her and she's growing resentful towards him because he's refusing her. We've tried everything, even blocking her on all network sites, but she just shows up at his door, standing outside his house like a lunatic! HELP!
