Hello, I'd like to help you with your question.
It is not uncommon for victims of domestic abuse to still have feelings for the partners that hurt them. You started the relationship with hopes and dreams that it would work out. Even with the abuse, you may not stop loving the person you are with.
When you learned that he has a girlfriend, it may have brought up the feelings you had for him when things were good between you. It also may trigger feelings of loss and loneliness. You had to make the difficult decision to call for help when your partner was hurting you. And even though that was a very smart move on your part, it does not mean you didn't suffer a loss when your relationship ended with him. You really did
not have a chance to go through a process of ending the relationship. It ended suddenly and it ended due to violence. That takes time to work through.
You also may be working through grief. You have suffered a loss, both of hope that your relationship would work out and of a partner. And although it is better you are out of the relationship, that does not mean you won't feel sad
. And now that your partner has a girlfriend, it may seem he got the better end of the deal. He has someone and you are alone.
You can feel better though by changing how you think about what happened. Focus on the strengths you have gained by ending the relationship. You no longer have to be in a harmful relationship. You took steps to free yourself. That is an accomplishment. Also, write down all the good things in your life now that you are free.
Also, work on your grief. You do not have to face what you feel alone. Try support groups, either on line or in person. Support from those who understand what you are going through can help you recover and help you feel less alone. Here are some resources to help you get started:

Also consider therapy to help you with support while you work through your feelings. It can help a lot to know you are not alone.
I hope this has helped you,
