Lonely At Home

My boyfriend and I have been dating for awhile we get along well no fights  our communication is good and  we have so much in common his family likes me alot right now each time I feel a bit sick they keep hoping Im pregnant which is funny as they don't know we are planning for a child but not for this year. I live in my own place and he lives with his mom and family, on the week-ends I stay at his place or he comes to mine anytime he has his own keys and at his house they like having me there when I return to my home Im very lonely and his mom wants me to come back but I don't want to overstep my bounds and invade his space , I want for us to live together but I'm afraid to suggest it to him as I don't want want to push him into anything he is not ready for , He loves me and doesn't mind having me at his home , His little sister is getting married and his younger brother just got married so his family keep asking when are we getting married and I just laugh to ease the tension as he has always said that he married me from the day we met . I don't know if he has ever thought of marrying me as he says very little and sometimes I think that if we eventually live together and things are ok sometimes marriage ruins a good thing but I am looking forward to the day when he will marry me or we will live together.
