Hitting my braking point

So I live in a little 1 bedroom apartment with my husband our 7 month old son. And my brother in law (who has tunnel vision) .our 3 cats and one from his brother My husband has a big heart.he is the sweetest man on earth. I love him so I put up with being home all the time. I hate being home i feel trapped. I love exploring and moving around and I never stay in one place for to long because I get bored and lose motivation to do anything. My husband's brother is an idiot who pays to go to work and refuses to get a better job. I want a little 2 bedroom house but no we have to accommodate his brother I dont even get attention because all this idiot dose is work and play video games. And has the nerve to wake up my husband at 10pm at night when my husband has to be at work at 0230 it annoys the crap outa me. Plus when they are together my husband gets aggressive. Like last night I have a studering problem when reading outloud and I am vary self conscious about it and my husband said the meanest thing to me I think he was just trying to look cool for his brother who was also picking on me for my studder. I have been holding back tears all morning and I cant kick my bil out because he doesn't have anywhere to go. And that would be mean. Bla bla bla I am so tired of being walked on because of him I want my house back I want my life back I am a patient person but oml it's growing thin. Oh did I mention how my bil is 20 and still acts like he is in highschool. I am tempted just to tell him to grow the fuck up. This is not high school anymore. This is real life get with the program.
