Op you asked for others experiences, well here is mine;
When l was 30 l met a seemingly lovely man, kind, loving, generous to all and pretty much perfect, until out of the blue after 10 months, with no argument prior he hit me, hard, across the face.
was beyond shocked but LIVID, and knew in my heart he was seriously dangerous, l dumped him then and there and blocked all communication, (we did not live together)
After trying all avenues to contact me and being blocked, l came home from work one day to find he had broken in, l was held all night, screamed abuse at, dragged around, hit etc.
Yes l was terrified but also so.very.angry. how dare he. Eventually at 5am l tricked him, escaped and hid until he had left my house.
Immediately l called the police, they came, l asked why they were not at his house as l wanted him arrested, l was told it was a first offence, only it wasn't, l found out he had done this multiple times, but no previous girlfriends had formally reported him. I made a statement and he was warned.
He stalked me for 6 months so l moved, changed my job, he could not find me.
However before the move he found me, l threatened to ruin his career by writing to the professional board of his profession, describing his actions, he would have been struck off (medical professional) if he ever contacted me again.
I also told his family, friends, my family and friends, as abuse thrives on secrecy.
I was devastated at being tricked into thinking this vile excuse for a man had made me feel like he loved me, it was all a lie, so yes l was utterly heartbroken and felt a fool.
But l had had many lovely boyfriends before, in fact all of them, and knew l would again.
For my peace of mind l tracked his whereabouts for 10 years or so.....
I was lucky that night, he could easily have killed me and l vowed if l ever got out alive l would shine a light on his behaviour and fight back from a position of safety.
Do not stay a moment longer than you have to, any day can be a day too long, when you feel powerless FIND YOUR ANGER it is your friend, it makes you strong and think clearly. He could kill your dog, or you, so get her and you out of there any way you can.
BTW l am 20 years married with 2 lovely teenagers, and have never felt scared since.
Take a deep breath, know this will soon be behind you and you will have your whole life ahead, with many lovely things to look forward to....
Call womand aid, call friends be very careful and get out, then report him, do not allow him to be in a position to kill someone else...
We are all on your side.
