Never good enough !! **rant**

I've been with my bf for almost 9 years (in april) when we first got together I was just about to graduate high school. My dad and mom divorced a few years prior and he left her with a lot of debt. She was a single mother raising 3 girls. When I graduated I didn't really have a chance to go to school so I had to get a job and pay rent.  My bf has always had a really good paying job. Getting into a union at 18. I met him in April 26th I had just turned 18 on the 9th and he was turning 21 on the 30th. I always had retail jobs or not great paying job/hours. At about 4.5 years together we moved in. Bought a house (all him of course) his grandparents gave him some money to help with a down payment and their only thing is that they want his parents on the title. He's an only child. It took me 2 years I find a job. I moved about 40 min away from friends and family , leaving my job being that I didn't have a car at the time. 

Fast forward to today, I am a full time student not working because my bf wants me to get schooo done and not worry about working. I don't like it but it helps me to focus fully on school. I'm getting my AA and hope to continue with my BA in early childhood education. 

His mom stopped working when he was 10 to be a SAHM. So for the last 20 years she hasn't worked. Everything seems to be HERS ! Yet nothing is mine. It's always his. His house, his truck (my name is on the truck and he was the co signer) his EVERYTHING .. she says it's because I don't work but yet I clean, cook take care of the two dogs. I do everything around the house while going to school. Back before he was born she went to school and worked (only took 1 class at a time) and because a preschool teacher when it only took a certificate to be. Now it's an AA which is what I'm doing. Me not working and going to school never seems to be ok. We aren't married and no kids. 

She seems to think we are always "to young" she had my bf at 2 years and before getting married , together 9 years getting my degree not married isn't good enough. 

She always says little mean comments and I've tried to talk to her about it but it doesn't stop. He has defended me so many times and still nothing. 

I have a really good relationship with his parents , we are always together , they spoil me on Christmas and bday. We go on vacation together and I've even been with them without my bf. 

I feel like nothing will Change until I start working but I also want a child like soon. 

Any words of encouragement ??
