Reoccurring fight

Melanie

My boyfriend have the same fight all the time, I try and tell him something that’s wrong and he just gets mad and ignores me. Of course this makes me even more mad and it always ends up with me screaming at him and getting no where. He claims all the time that we’re in an adult relationship and so we should do adult things like trust eachother. He wants me to trust him so that he can go to his friends house even when they invite over his ex’s, girls he used to like, or girls who are there just to get laid. His friends won’t let me come, and he agrees that I shouldn’t, which all leads to me not trusting him. I use this as an example as to why he needs to communicate with me: if he feels that we’re mature enough for me to just trust him blindly than he should be able to communicate with me. But still, he always says nothing. How can I get it across to him that communication is extremely important in an “adult relationship”?
