Husband distant

So lately I have been feeling like my husband just doesn't want me anymore. I'm 23 weeks pregnant and I can't decide if it is hormones or what but I feel like he has stopped doing the little things. Like giving kisses and hugging me out of no where or touching sometimes go to bed without saying good night. I talk to him about how I feel and he says he is sorry and that he loves me with all his heart and that he will try to make me feel a little more loved. But it has yet to change I just don't know what to do. It just feels shitty feeling like I'm in love with someone who possibly doesn't love me back anymore?
