what do I do

Today me,and,my husband were arguing because he dosent trust me, when I go out because I'm around other men(his ex wife cheated on him multiple times with multiple people).I love him a lot but, I want to earn his trust, I never did anything to lose it.we've been,married for almost a year and a half and we've never had issues like,the ones were having now. He's jealous of my best friend who's also a male, when I've gone out he's showed up or wanted me to come home telling me its an "emergency". The man I,married is not the man I met in college. When he showed up at the restaurant, I was at with my friends , we went to the parking lot and arugued. I went to my car ,drove off and cried . I pulled over by the side of the rode and sent him this.
