He gets so mad

Whenever I bring up something that bothers me he calls me insecure . History of disrespect and cheating and etc. I am a little insecure and I hate that for my self. He has done me so wrong over the years and I take him back and hope things changes. He had my number saved as rat snake when he was mad at me during an argument and that hurt my feelings . He said I’m a snake for going in his phone. We’re married why so many secrets and why keep women in your life that you may have dated or tried to sleep with on Instagram etc. I am married and trying to save my marriage . He said I make him want to leave me when I bring up anything I discovered he has done . He’s not nice he’s not reassuring he only wants to have sex of course and give me a little money twice a month for bills like $150 which covers maybe one bill. I’m so depressed I think I need a therapist
