Mom doesn’t approve?

So I originally got married at 16 so I could be legally emancipated and my mom was on board with it and even encouraged me to have a baby at 17 even though my husband got pretty abusive after we were married.

Divorced him at 18.

I’m 22 now and I’ve known my boyfriend a year now and we’re planning on getting married so we can stay together (were military and he’s about to PCS) I told my mom about this and she lost her mind. Says he sounds controlling since he wants to marry me so soon. Also what my mom doesn’t know is I had a miscarriage last month. we’re talking about trying for a baby now and when I brought up to my mom that I was beginning to think about kids she lost her mind and told me I was too young to be married or have kids. Keep in mind I also haven’t seen my mom in two years as I’ve been stationed over seas my entire career so far.

I’m just kind of upset, she pushed me to marry someone I didn’t know when I was 16 because she no longer wanted to be responsible for me, and now that I’m with someone who actually cares about me I’m suddenly too young?
