Hi Vegansphynx. I saw your post some time ago. Sorry for your condition.

Your master degree is NOT pointless, but he is. You can use your degree to get better career and better life. And him? You have realized that he gave you nothing but pain. He only used you. This separation is your OPPORTUNITY to be free from someone toxic like him. You must use this to build a better life.

Please be kind to yourself, by finding someone who's able to love you back, appreciate you better, and treat you well. I believe you will find it someday, and then you'll be thankful that this separation ever happened.
