Hi @Jhett707,
I left my former partner after 13 years of unhappiness together and I am so glad that I did. During the last few years of our so-called 'relationship' I was suffering from major depression. I had to get treatment for the depression as a matter of urgency, so I actually stayed with my partner while I trod the long road to recovery.
My psychiatrist even told me "don't make any major life decisions while you are still depressed." I think this was good advice. Things were so much clearer to me once the depression began to lift.
@Jhett707, are you seeing a psychologist or counsellor? You need to talk things over with someone you trust and who is unbiased. It would be good if you can start to rebuild some bridges back to your own family, too. A counsellor may be able to help you with this. Start small, with a phone call or text to a family member you were once close to. They may be very happy to hear from you.
Work on the things that you can change and that you do have control over, for now.
Seek legal advice before you separate, not after. Get to know your rights.
When I left my partner, I gave up everything. Thankfully, we did not have children. I had worked hard and paid around 70% for our joint property. I never saw a cent of this, because my ex-partner's Dad was very, very clever and tied up our property in a trust associated with his family business. He was the one who had all the money and the lawyers. I could have fought him for my rights, but I chose to walk away and make a clean break. I don't regret it.
I was just glad to say goodbye to 13 years of misery and lies. Even loneliness was better than being with my ex.
Please, please seek help with your depression first, then begin to make your life decisions with the proper legal advice and the support of those you trust.
