Hi I honestly don’t even know where to start but I’m currently really looking for advice!

So I am 30 years old me and my boyfriend have been together since I was 19 and still no ring but that’s another topic. So my boyfriend is the middle child and let’s just say he’s the more responsible one of all the siblings. He has a older sister who doesn’t have custody of her children and who just lives house to house with family and he has a younger brother who was abandoned by their mom at the age of 15-16. So as of recently my boyfriends brother was told a year in advance that he would have to move from his building and he was searching for apartments in the midst of everything he got fired from one of his jobs done to an assault he did on his ex girlfriend. He then still had a income. So the day he has to move out he tells my boyfriend he has to stay with us and like who tells you they have to move with u when they move their stuff out. So then he just calls me and tells me his brother has to come and then one week after his brother comes he quits his job . My boyfriend works a lot so when I come home I have to see his brother sleep on the couch after I just worked all day myself and I have a son and the house now always smells of weed and me and my boyfriend don’t smoke. His brother then gets another job after months of just Laying around our house while we all are gone and he quits the first day and mind you he has a record he says ge wants a job making 100000 a year but he has felonies and a ged as a woman I really just want to leave the situation I know family help family but this is enabling he is a grown ass man and he gets to not pay us nothing. Collect unemployment and smoke all day like I really feel so uncomfortable in what use to be my happy space like I just don’t know anymore. I also feel like I basically had no say so in the whole situation
