I’ve had something similar
my son (now aged 22) had a girlfriend just before lockdown #1 (they where both about 20 at the time)
im the mum who’s there with advice,money and support etc but believe my dc have to lead their own lives
anyway,the girlfriends mother is batshit
i live 100 miles away from my son,so he said he and this girlfriend would like to come and stay with us for a week
fine-no problem-she was driving down with him and the dog
ive never had anything like it-the mother was video calling me on fb for weeks running up to the visit
she wanted my address,work address and phone number,my salary,my dps salary,what we did in our spare time,who else lived with us,my life history,any criminal records she needed to know about-the whole 100 yards-this went on for weeks-I’m amazed she didn’t want to know my bra size
i refused to give this info-she didn’t need it and the girlfriend was 20 years old
anyway,mother tried to ban girlfriend from coming,then took girlfriends car (drove it away) and only admitted what she’d done when girlfriend said she was going to the police to report it stolen
a lot of grief later-they finally got to us
the girlfriend had to ring her mother over every small thing-what she was having for dinner,if we went to walk the dog,if we went to town,if we went in my dps car-every 5 minutes the phone was going off
then her phone kept lighting up-turns out the mother had put some form of stalking device on the phone-and was reading texts/messages etc
she had a tracking device on the girlfriends car as well
I’ve never in my life seen anything like it
they left two days early as the mother kicked off
thankfully,they broke up a few months later-the mother demanded it and the girlfriend just went with it
i swear this is all true and I hope the girlfriend escapes-she just seemed to think her mother was ‘strict’
my sds mother was the same-sd was 17 and came to live with us briefly
we don’t live near her college but it was a 5 minute train ride away
her mother went looney at us for paying the fare but ‘making’ her catch the train
we where meant to drive her every morning to college-pick her up after,cook her dinner,wash her clothes,sort out her college work for the morning,make her lunch,wake her up the next morning,lay her toothbrush and clothes out,cook her breakfast and drive her back to college again
sod the fact we both work full time and couldnt (and I wouldn’t) do all this
but the fact the poor petal had to walk 10 minutes down the road and catch a train was beyond her
and she wonders why sd has zero life skills and is struggling at uni
