Is there anything I can do to save my marriage?

My husband and I don't get along for the most part. We are always arguing. He rarely does anything for me anymore. Like I don't know when the last time was that we went to dinner. He is so lazy most the time. He complains that I complain too much. I have been going to therapy to help with managing my stress. He should do therapy too but says its too weird, but yet he wanted me to go. I am always giving giving giving and he is always taking. It is a very one-sided marriage. If I bring anything up that I don't like that he is doing, he finds ten things wrong with me. Things have escalated so much that we had a big argument in the line for Its A Small World at Disney. We have a 14 month old and I really don't want to take her away from him, they are great together and he is a great dad. I also do not work, and we just bought a house. I feel like nothing I do matters or helps. I am a perfectionist when it comes to making others happy, so much that I sacrifice my happiness. What happened? He used to be romantic and cared so much about my feelings and then something happened around the 3rd month of our marriage that he started becoming addicted to porn and then I kept catching him and I just don't get what happened in the first place, what made him turn to porn. We have always had an amazing sex life, so what was his need? I am just so confused. We have been married 3 years now, together for almost 6.
