What do I do

My husband and I have been married for a while now and he is very big on respecting each other .. but it feels very one sided … all he does is mess around watching porn and retweeting naked picture of girls and then dares to tell me I’m being unreal for being upset about it or for feeling insecure… if I even dare to like a picture of anyone and there is a guy included or if I’m even following a guys he flips shit ? We got into such a heated argument about it he went off and told his mom and sister and then they all decided to gang up on me even though they kept telling me they weren’t taking his side . All they said was that I was the toxic one in the relationship because I lack communication and confidence… I’m very convinced it is me and maybe I’m overreacting???? WhAt do I do.
