Relationship Advice

Hi!

To start this off I ask of everyone to keep an open mind and to please not judge. My boyfriend is a diagnosed sociopath. A lot of people would say to leave as the first response but please hear me out. My boyfriend is a diagnosed sociopath and obviously wishes he wasn't, he can't change it only treat it. I give him all my attention, my constant reassurance and love, give him sex at any moment. I just love him. Many times he makes me feel like a queen. He's chivalrous, charming, funny and attractive. Though there are many times I feel empty, unwanted, and unloved. He needs constant stimulation so he looks at half naked women online all the time, needs flings and wants threesomes, has put me down for my past dating experience with another girl that happened nearly 3 years ago, and when he gets angry it gets really bad. I feel insecure and terrible but at the same time he makes me feel like im the best thing that has ever happened to him. He motivates me to work out and eat better for my overall health, does worry about me, can make me feel as if Im the only one he looks at yet can also makes me feel like Im the absolute worst. I know he tries hard to make me feel better and make me comfortable because of his condition so please don't tell me I should leave him, end it, or I should tell him to "f**k off". Im here to fix this relationship and help him with a disorder he was born with because I can assure you both of us wish things were easier and different. Im here to stay by his side and help through thick and thin, sickeness and health. I just need advice myself. Thank you💕
