Feel deprived of love. Help me, please.

I'm married for 2 yrs now with 15 month old baby. I feel things have changed in the last 2yrs... People have changed, my husband especially. He doesn't seem to care about me like he always did before. I have discussed this with him several times but somehow things don't seem to hit him. I can sense that we have lost the connect, probably because I moved with parents post delivery and I get to meet my husband only over the weekends. Besides, he has always chosen his family, for that matter everything over me. I don't feel like I'm an important person to him, at least his actions don't give me an assurance. He gets upset for little things and reacts for everything. I feel extremely hurt. I don't want to end my life coz I have my son; he needs me. Too many things running in my mind, is driving me crazy. I don't want to give up on marriage coz I really love my husband. Can someone really help me, please.
