Doesn’t want the attention ?

I’ve been together with my boyfriend for almost 9 years now. We have lived together for four years. He was diagnosed with autism. so we’ve talk about marriage and he said that he wants to get married to me, but doesn’t like the attention it brings.  I understand so that’s why I offered to make a sacrifice by us having a wedding that no one goes to like just a quick courthouse wedding. What I really want is just to be married I don’t care having a nice wedding anymore.  I don’t know what to do because I feel like if he doesn’t wanna get married because of the attention that attention will never go away like it doesn’t matter if we get today or 10 years from now you still get attention from others. I feel like I’m getting more attention with everyone asking me how come we haven’t got married since it’s been nine years. I even said as long as we’re engaged I’ll be happy. We both want kids but apparently that’s one of the reasons he doesn’t want to try to have kids right now is because it brings attention. My only dream in life is to be a mom. I love him a lot. I’m just scared. I’m wasting my life waiting on him and it might never happened. Or I have a fear that by the time he’s actually ready it will be too late to have kids (like we are older and ended up having issues with getting pregnant) Am I making this into a bigger deal than it is?
