Family problems please: 06/28/62

Hello .. I am feeling so lonely and depressed..I have been married for thirty plus years and I still have fights with my husband whose birthday is 03/10/58.I feel I am not important to him and he can be very abusive and a hot temper. I have to watch constantly not to disappoint him,he also does not like my side of the family. I am so confused as I How I am suppose to live my life as hassle and stress free. I am also currently suffering from insomnia.. I sometimes feel that I don’t have any support even financial wise because he knows that I work. He already told me that he can not afford me. Please help me I am so, tired and stressed out.
