My husband is suspecting me, I want to quit

I am 40 year old housewife. I have been married for 14 years with 2 children. We are a well to do family. I have had issues in marriage even in the past, but for the sake of children, I have been putting up with my husband. He has tempermental issues. He disrepects my family, meaning my parents and sibling. It is not that he is bad. But there are trust issues. The first and second time he suspected me, i was hurt. But again my children were my priority. Now the third time he is accusing me of staring at my neighbour. for real?? ridiculous. During this lockdown, it had become a ritual for all of us to go to the terrace in the evening. My children would play and we would walk. There were other people in the locality who would, also, come to their terrace. I don't know what went into my husband's head, he said he saw that the neighbour was staring at me and I was responding to him by looking back. There is 0% truth in this. My husband doesn't talk much, not very social. But his mind is always cooking up stories. I want to leave. But my children, I don't want them to go through this trauma of divorce etc. They have a well settled life her. I am well qualified and can financially be independant. But my children will not get all the comforts they are getting now, if I quit. I cannot live with him. There is no love in this marriage. And mutual respect is also dying. Please help.
