I agree with what something2say says. She knows. please listen.
Now.
I'm going to rant, not at you OP, at your situation.
firstly, with respect, your parents are arseholes (Mine are too, as are MANY DV victims, it's not an accident)
Ultimately you need to get the hell away from your parents too, as they are only hurting you further. Your mother, by not doing anything to stop your dad is enabling him.
How dare your father say such shit to you.
Is your ex withholding his number when he calls? If not, then you can get Caller ID for next to nothing and never answer it, better you can get free voicemail and let him leave his poison there... then you can report him.
Tbh, you can have him blocked if you report him for harassment. Speak to your phone provider.
If he withholds his number, get the block that stops withheld numbers, it'll be cheaper than £13 pm I'm sure. Offer to pay it.
Next. YOU.
My love, you have been abused as a child by your father, and by your ex. these crimes leave huge marks on our esteem, and recovery is slow, painful but can not be left to get better on it's own. If you do nothing to heal yourself, you won't heal. You left your ex this summer? The ONLY relationship you need to have right now is with yourself.
This is not a judgement, not by any stretch, it is fact. You are NOT ready to have a relationship with anyone. Not this soon. It's OK, you weren't to know. The minimisation you and all those around you have done to convince you to keep on allowing them to hurt you is hard at work during the early days of your recovery too.
What you need to do now is STOP. Breathe. LOOK at the fact that you don't have this vile Ex in your day to day, and how your life has really improved as a result. LISTEN to your instincts, to your gut feelings about how life is now and how much better it is to be in your skin now that you are free from this abuser.
Your boyfriend isn't important, he's of no use to you. OK so you weren't ready for a relationship, and kept relying on him for reassurance, that's normal, any guy with half a braincell would realise that. The guy you were with is not 'the one'
for now the only ONE there is, is you.
Get yourself some counselling through your DV contacts, don't give up until you get it. It's vital to your recovery. Sametime you need to do the Freedom Programme. OK it's not the magic bullet we hope it is, but taken in conjunction with DV counselling, reading Why Does He Do That by Lundy Bancroft, and Power and Control - why charming men make dangerous lovers - Sandra Horley create a complete, intensive surround-sound healing experience.
I'm 2.5 years out of a DV relationship. It left me panicked, agoraphobic and isolated. I did all of the above and attended a DV recovery group. It was hell on wheels running from one appointment to the other, but the progress I made was considerable. I also posted extensively on MN, and the support I got here was invaluable.
I've had a year relationship with a non-abuser, ultimately it wasn't right, so I ended it, but even in my mid-40s, i wasn't written off!
Single now and happy to be so, I'm enjoying my life and freedom, working hard, spending time with my son. Life is good.
Funnily enough, all the work I have done, all the realisations I have made wrt my awful family, and pathetic ex, who I know now all abused me from a position of inferiority and weakness, not strength and power, have made me a stronger person, and emotionally/psychological more robust and powerful than I have ever been in my life.
I am chair of a DV charity, I have given speeches on DV to the Armed Forces and GPs and in many ways I am BETTER off now as a result of my experiences than I was before.
I know that you have a long way to go until you can reach this place, but I want you to know that you have done the right thing and when you allow yourself to start to heal and release the pain, there is a happiness waiting for you that you can't even begin to ever imagine.
No compromises. If anyone isn't 100% supportive of you, AVOID them, cut them out of your life if you need to. Put yourself first and foremost.
It gets OHHHHH so much better. Keep strong, keep posting, we'll get you there!
