This is going to be a long one, sorry
Difficult relationship with Daughter who is in 3rd year at Uni, partly due to ex brain washing her and doing everything in his power to make me look evil.
DD asked my DSis a few weeks before she went back to uni after Summer to be a guarantor for her uni accommodation, she couldn't do it as only works part-time so she asked me and I agreed.....even though she hadn't spoken to me for over a year at this point. Met up with DD for 5mins as she was loading her stuff into her boyfriends car and she agreed to keep in touch. A few messages were exchanged on her way to uni and once she was settled I messaged her to see if I could send her some money. She provided me with account number and sort code and I transferred a couple of hundred pounds into the account and received a "thanks x" by text.
I have text a couple of times in the last month and had one word answers, all ok as at least there is some communication.
Last night I happened to wake up at 5.30am, checked my phone to see a missed call and voicemail from her number, message was 2 mins of muffled music. Rather than call back I sent text asking if everything was ok and got an immediate reply saying "can you lend me some money". She wanted me to lend her £100 or as much as I was able as she was struggling with bills. I agreed that I would sort in morning when I was awake. She then carried on the text conversation....which I thought was strange as called me "babe" at one point!! She offered to meet up with me again when she was back and she wanted me to meet her boyfriend as I had only met him for a few seconds. The last message I sent was delivered but not read.
Throughout the day I've had this weird feeling that it wasn't her texting which was confirmed by my DSis when I asked her to check the number. DSis called her and at first she claimed not to know the number, then she said it was her boyfriends number and now she is saying that she never sent the account number a month ago and "someone" must have used an app to change their number to hers to send their bank account details which I have then used to transfer money over to. I'm so confused, how could this happen, is it even possible, especially as she is now texting me from the same number??
