Yes i have dealt with that before. This one friend and i were really close, we used to take the train to Berlin to get away from it all for weekends, we used to go do some fun shopping and dinners, we used to have a blast!!
After she and her husband got divorced she met another man, well that was it!! She had no life anymore, after meeting him several times, i got the feeling that she was affraid of him.
I asked her straight what the deal was with him, she admitted he was very jealous!! A few months later i found out he was beating her up. Her daughter told me that when he drinks he gets angry and starts fighting with her mother.
When i asked her about it, she said it was no big deal, and skipped the topic.
They moved to another part of Holland, i now only have occasional email contact with her, because she's not "allowed" to use the computer when he's not around, so he sits with her while she types my mails, probably to watch what she tells me.
After she makes phone calls he checks the numbers she's dialed.
Sad but true
