you have to leave them mate. violence in a relationship (or anywhere) has no happy ending. shut the door, don’t look back, and walk away. the only cure for a broken heart is a new love in your life. mtfu is a joke you know that but get back on the horse is sound advice.
[this isn’t from personal experience, this advice comes from helping my best mate through, out of, and after, a really abusive relationship. he is a big bloke and im proud to say he never rose to it, even when i had a phone call when he had locked himself in the bathroom and she had the kitchen knife out. he really really loved her and couldn’t see past the relationship, but he is a very happy boy now, and im sure you will be too. most people dont treat each other like that]
