is it time to let him go? long post please help

me and my husband been together 8 years..but the past year has been really rough for us..a month ago we decided to give eachother space..meaning he moved out.."i know horrible idea but we both agreed." the reason for this space is because of trust issues and he has bad habits like smoking, drinking, he goes out with friends and iam always by myself at home..he also gets home late..so that was really affecting me mentally because i did not feel loved and felt lonely so that is why i agreed to have space..and he says that he does not want me over him meaning "he dont like for me to tell him wat to do" and that is his reason for his space..so anyways about a week ago we agreed on going to counseling in may..but still be separated..i dont like the idea of still living separated but he said that he does not think we ready to get back together.. because of trust issues which i agree..BUT at the same time he keeps doing what caused this separation so now iam confused..today i told him to come watch a movie with me and he agreed but only stayed for an hour..he said he was going out with friends..and he knows how i feel about that..i just cried because i really feel like he dont want to work this out..any advice? thanks
