Feeling not loved

My husband and I for the past 2 years have had serious problems due to his drug use and drinking. He's back home now and we are now expecting our 4th baby. And I just dont connect with him. I'm so emotional and need love and assurance of it and he doesn't provide that for me. We've been together for 14 years maybe he's just tired of me? But I wish he stepped up and met my emotional needs. I'm tired of being the one to reach out to him. To be loving to try and fix things. I dont feel that any more. Am I falling out of love?? And the thought of that makes me feel worse! I'm just hurting and feeling just not loved!
