Why does my ex's new girlfriend keep calling me and sent me a text?

Well she obviously isn't a good mom if she is exsposing her child to drugs and wont let him man up and be a dad to you guys baby.. honestly if i met a guy i would encourage him to be there for his kid.. its wrong not to be! He's a worthless dad if he isn't there and if he is letting her do this. Get over him he has obviously proved he is worthless so take him to court and make him pay child support and if she keeps calling save all the text and file harrasement against her.. It will be the best hting you can do. She sounds immature for her age and jelous call cps on her kids if she uses drugs too.
