Need opinions!! Don't judge

My boyfriend and his ex have a son who is five. It's kind of hard on me I love the kid to death. Me and his father have been together for 4 years , he is 25 and I'm 23 and in school plus working full time.

I've always wanted a baby so bad I had a miscarriage a while back so I guess that's why the jealousy comes in to affect when I think about him having a baby with some one else. Because I love kids so much and have always dreamed of being a mom

When I mention it to him he says I'm crazy and need to wait until we are married and at least in our late twenties.

Sounds reasonable but I just want a baby so bad. And My selfish self gets mad at him because he has one with someone else - makes me feel like I'm not good enough.

Please don't judge I know I sound like a terrible person I suffer real bad anxiety issues but I do have a good heart . I know I sometimes sound cruel just wish I didn't

Sorry for the rant but am I over reacting not wanting to wait that long? I'm the only one out of all my friends tht doesn't have a baby :(
