Need some advice.

I feel like my husband just doesn't seem to care anymore. Tomorrow will be our one year anniversary and he volunteered to work. My birthday was in may and he had it off but volunteered to work. I just dont think i have a place in his life anymore. We have a three year old together and i want more but he doesn't. I cant sort through these feelings that i have and it hurts. In February I had a miscarriage he didnt even stay with me at the hospital he went home cause he had to work the next day well i went in the hospital again the next day he didnt even bother coming with me cause he had to work. I had no support from hi m emotionally and i just think he's completely checked out. Any input is appreciated thanks in advance.
