feel like my husband doesn't love me anymore

I feel like my husband doesn't love me anymore. He isn't as affectionate as I thought he would be during my pregnancy . He constantly argues with me and ignores me sometimes . I thought he'd be rubbing my belly , talking to the baby, be lovey but it's been the total opposite. I feel like I can't talk to him and I feel like he doesn't want to spend time with me. This is causing me to become depressed, stressed and lonely .
