She was dating a guy for 3 years( he was the other guy while married) and she broke up with him bc he was putting his hands on her till she pass out....now she met a nice man on november 2015 and everything was going good till the ex boyfriend emailed her. I tols her to ignore it but she didnt listen...she met up with him and they had sex for a whole week( she told me )and now she is pregnant...she told her current boyfriend she is pregnant making him think its his baby but he said he is not ready to be dad and its now how he wants to have kids. She than called the ex who is the dad and told him she is pregnant and he said he can not be dad bc he only had sex with her for 7 days lol....now she told everyone at work everyone ia giving her different talks...idk what to do? She is acting weird with me now bc she asked me to do i feel some type of way since she is pregnan and am not?(i had mc last june ) i am happy for her that she is pregnant but she have more important things to be doing than fucking different men. She have 7 year old in school who is not doing good in school. She have 4 year old who is cutting her hair for attention bc my friend is spending more time with the current boyfriend every weekend....idk what to do anymore?part of me dont even care anymore....she always say that i am married and have nothing to worry about...but she can too have a good man in her life if she gave things time and stop fucking men just for fun....sorry ladies i am mad and hurt at the same time...also she told our co workers she is getting abortion but when i asked her she told me she will let me know what she wants to do once she hits 5 weeks...
