I went a bit over the top about her mental state and intellect after realizing it was her own number and the simple fact she should've known she was calling me from it, lol. As far as apologies - from memory, she equivocated far too long during my initial confronting her about it - even pointing it out to her and ringing her phone in front of her she went mute and still blamed me for not knowing earlier - like wtf . Long story short, by the time i was finished no apology was necessary. When i look back now - holy shit - what a mess i and some of my relationships were.
