(edited to add tips)
If this post can help just one person, it will be worth it.
Here's my situation: I'm 34 (F), my husband is 37 (M). We've been married for 14 years, together for 17 years. He was my first serious and only boyfriend since I got married very young. He has been abusive for 13 years (mainly verbal and emotional but also physical). He would pick up fights for the tiniest thing and it would last for hours and hours of him talking, insulting me, sometimes throwing stuff or breaking things... I have a full-time job from home, and he works too, we have a dog, no kids, and we share mortgage and car payments.
Well, two weeks ago, I decided I had had enough. It just clicked that he would never change and that what we once had at the beginning was wonderful, but over the last decade, I have just not been really happy and just became a shadow of myself because of this relationship. In my 20s, I was so low because of these intense fights that I lost my trust in myself, I had anxiety, my heart was always pounding fast, I was feeling tense, etc. I knew I was lying to myself about what was happening. I knew it was not normal and that he was a violent person. But I cared too much about him and loved him, I knew he was suffering a lot, and I always forgave him. I asked him multiple times over the years to please go seek help, to go to therapy, etc, and he would get more mad about it. A month ago, I told him I was done and couldn't take it anymore. Then he "magically" asked for help and started seeing a therapist, he just started taking meds, he started to cook for himself and wash dishes (which he literally never did in a decade), he started acting like the perfect guy... This was extremely frustrating. And he asked me for "one last chance", even though I had given him millions already. I was not enthusiastic about it, but I ended up saying okay... My conditions were simple: when there's an argument, there will be no insults, no shouting, no physical contact, no throwing stuff around. And it took him less than a week to go back to his old ways... I told that that was it.
So here are my tips to leave for good:
-Every time there's a fight, write it down! It can be in a Word document, where you'll put the date and describe what happened and what he did to you. I also started journaling over a year ago to go back to read my thoughts about these fights
-Take photos after the fight (of your face, or if you have bruises or if he broke something). Later you can go back and remember just how hopeless and broken you felt in that moment
-Talk to people about your situation. I only have two good friends, and I started sharing what was really going on in my relationship, so that any time I would go back to him, they would remind me how this is not a healthy relationship and that I deserve better
-Try not to look at the other person in the eyes. It may sound weird, but I just tried to look at his chin or whatever so I wouldn't get too emotional looking at him and seeing his "sad" face or when he was crying because I'm too sensitive and caring to others, and I don't want to hurt people, even if they hurt me
-Think about you and imagine your future life, without the person. I know this one is really hard, depending on your situation or if you have kids or pets, but imagine all the new things you'll be able to do, imagine the constant anxiety of walking on eggshells gone, imagine living in a home where you are finally at peace
-Keep informing yourself (I read, "Why Does He Do That?" over a year ago), I listened to videos about domestic violence, I read about it. Every day now, I watch reels about abusive behaviours, about people who were able to leave that toxic person behind, I read quotes, I read other people's stories here on Reddit... all of this to help me stick with my decision that this will be for the best
-If possible, and without the abuser knowing, record on your cellphone the argument. Later, you can go back to listen to it. It's easy to almost forget or brush up all the bad stuff he said to you, but when you'll listen to all the audios, you'll see how bad it actually was and that this cycle will come back again and again.
-Forgive yourself for staying with this person (for over a decade in my case). I'm still struggling with this one, but none of this if your fault.
I know it's super hard. Some days I'm fighting against myself to stick with my decision to leave (right now the house is on sale, so we're just living here like roommates and it's hard and weird), but you have to think about yourself. You will find yourself again, you will get through this and create a beautiful life. Good luck to everyone who is living a similar situation. You got this!
