I think my husband is very high temper person. He just hit the car at home and complaint a lot toward my dad. How should I do?

More than anything, your husband probably needs to know that you’re on his side, that you’re not against him. Being calm in these situations is really important! You may need to communicate, more than you probably think necessary, that you accept him and love him, even though you may not be satisfied with his recent behaviours. Try to find out what's making him so high tempered, work, friends etc. Then you can try to help the situation!
