Almost like I sought out a person who treated my like how I was as a child. Ignored, disinterested,not valued, not loved., getting shouted at for no reason. It's honestly astonished. It's as though subconsciously I chose that,but I don't know why I would.
Because familiarity is our comfort zone. Even when the familiar thing is bad for us. To progress to a better life you have to step outside of your comfort zone, lots of people find this incredibly difficult. If your comfort zone is full of a lot of things that are toxic, you've got a lot of hard work to do just to get to a baseline that people who have never had that toxicity in their lives have as their "normal" and their comfort zone.
The way I see it, you can't change your childhood but you can take steps towards changing your adult life, learning to make better decisions and choose the non-toxic option. It doesn't have to be dramatic either, although it can be if you want.
You mentioned not loving your husband, so you could start the divorce process tomorrow. Or you could look at how to alter your week to carve out some me-time to start a new hobby, to raise your confidence in yourself, whilst accepting that your husband is going to make that difficult and kick back against the new you. As he's abusive that likely means an increase in abuse, so the chances are you'll divorce anyway one day. I know it sounds daft, but if it suits you to choose to stay in an abusive relationship for some reason eg until you've got a job or a qualification etc then you can choose to do that.
It's your life and you can choose to do what you want with it because ultimately you do control your own life, realising that is the first step to changing things. I used your marriage as an example but you can apply it to all areas of life. If you can't face changing big things, start small. Look at your life and decide to change something for the better, it all adds up to the bigger picture improving. Eg a person who smokes will have more disposable income if they quit, meaning more chances of being able to eg pay for driving lessons to increase independence or save for a dream holiday they've always wanted to go on.
So many bad things have happened in my life but I found the key to survival is to look at what can be changed. The things that seemingly can't be changed, look at the barriers to the changes and see if/how those can be changed, there's probably a way, although you might decide it's not the best choice for you to make. If you want life to be different you have to change things.
I think it's possible to change a sometimes faulty decision making process by committing to being kind to ourselves. It's not the same as being selfish and ignoring other's needs, it's deciding whether that particular other person's needs are my responsibility in that particular situation and, whether they are or aren't, asking myself as I make any decisions on what to do "am I being kind to myself?". Otherwise I find all decisions end up being about others and leaving my own welfare out of the equation.
I don't believe going through adversity makes a person stronger. It can make a person more resilient upto a point, beyond that though it makes them damaged. Then they survive and make a good life (if they do) despite the damage that was done, not because they're somehow stronger for it.
