Not in love?

I am married about 6 years. And now we have difficulties in relationships with my husband.
He stopped spend time with me and our child, getting be absolutely impatient to our little child, doesn't talk to him normally and doesn't want to teach him anything.
I always tried to be a good wife for him, cool dinners, clean and repair our house without his help, work full time and study at nights, taken classes online and soon will get my degree, take care of our son and please him on the bed. I am open for anything he wants, but he barely wants me.
All he loves (!!!) to do is to play chess. He can stay on his office room all day and night, in summer he also stays there playing chess. Never wants anything new, any activities, travels, etc.
At work I met a guy who followed in love with me. I like him but let him be just friends with me. But so far my husband abandoned me so far I need more attention from my friend. I feel awful about it and afraid to think that my marriage is over. Million times I spoke to my husband and lately I see that my words don't go into his heart. Seems, he should be happy if we will be gone someday.
I love him very much, but I don't feel anything from him. I spoiled him a lot. When our child was born I never asked him about the help. And never asked to help me cooking, cleaning, repairing and he never offered it as well. Now he doesn't want to do anything.
He did a lot for me and I appreciate it. But something is going wrong between us now. I don't know how to help us if there is still anything to help... I feel awful and lonely..
