What would you do if your live-in gf stayed in close contact with her ex gf, and would not break all contact even at the risk of losing you? This would not even be a problem if the live-in didn't habitually lie about the contacts, and hadn't done some really bad unmentionalbe things on cam for the ex. I should also mention that the ex has BIG hopes of a reconciliation, and stops at nothing to cause shyt between my girl and I. This has been going on almost 2 1/2 years, now.
