Violating privacy

So my husband wants to see my history on my snapchat bc he doesn't trust me due to recent events, he has a history of snooping and manipulating, mind fucking, psychological abus. He promised me a few weeks back he would stop with snooping. Now he wants to see my history on snapchat. Bc he thinks I'm hiding something. I havnt been hiding anything I send stupid a snaps to family and friends. He thinks I'm secretly messaging someone els, such I am not. Is he violating our agreement and my privacy
