Selfish Husband?

My husband and i went out to dinner the other evening and i started to discuss some things with him that we needed to adress i did not mention it at home because his free loading brother has been living with us for a year so i wanted privacey. our lease is soon to expire and he wants his brother to come with us to our next apartment "he is 29 brother" me 26 and I said i need space and privacey and i was not comfortable with it anymore and i feel like he is pushing him on me in addition my husband perfers to only party with his friends and does not invite me to parties, bbq or anything and when i asked him why he said it was because he wants to be himself however we dont go anywhere at all. I am to the point of no return and i feel that the best solution for the both of us is to go our seperate ways, I want a diffrent kind of man in my life a diffrent kind of love right now all i feel is sad, loveless and bored, i am only upset with myself for taking so long to realize this. any suggest
