Husbands ex

Super pissed I really need to vent. So my husbands ex is seriously obsessed with me. She got married 2 weeks after my husband and I because she wanted to be married to just like me. She died her hair the same color as mine and got the same car as me and comments on all of my social media stuff. She sent me letters when she went to basic training too like no we are not friends. She found out I was pregnant about 2 months ago and decided to message me asking me advice on how to get pregnant. She knew I had a miscarriage on 11/01 and she knows I've been struggling with it and she decides that it would be appropriate to message me today to tell me that she is pregnant and that she is due on mine and my husbands 1 year marriage anniversary and how cool that's is and how happy she is. Like congrats bitch. Ughhhh sorry just needed to get that out.
