When he wanted to contact u then respond to him. When he cares about u then he surely loves u but not showing . You are feeling alone because u need someone to listen all ur problems and be with u as ur backbone and it can only be ur husband. Dont forget communication always connects the people and silence separates. He has done faults but knowingly or unknowingly he thinks about u a lot. So talk with ur husband then u can be in touch with him.
