ex-Gf has been on birth control the whole time we dated. I just found out this past weekend she had a miscarriage in jan. She has been on antibiotics for about 1-3 weeks. I know that increases the chances big time, should I be concerned at all, or not really? *secondary question* If a girl says they want space, and acts like two different people, and has new male "friends" then pretty much the sun has set on this relationship right? *side story..* She said she wants space, or otherwise it wouldnt be a problem because we WERE on our way to getting married (had talked it out, and were about to get back together) but apparently i don't think it is in her plans anymore.
