Feeling unwanted by my husband

So first off, I'm posting anonymously because there are people on here that know my husband and I.

A little background:

We have been together since I was 15 and he was 18. We're now 19 and 22. We have been married for 9 months now and in the beginning it was amazing. But it's like now he just doesn't want to spend any time with me. He always finds excuses to not come home or even come lay down with me. I'm just feeling so unwanted and just don't know what to do. I've had so many conversations with him about it and it seems like it's not a big deal to him. I get he needs his alone time too because I need mine but it's just ridiculous. It makes us fight because I just get so upset and he doesn't care.

I also had a miscarriage (our first pregnancy) two weeks ago and it's like he didn't even care. I just needed him there for me and he didn't even come with me to the hospital.

What do y'all think? Anything would be helpful. I don't want to be divorced before 20
