any advice?

me and my husband have been together for almost 5yrs. I'm currently pregnant 20 weeks and i decided to move out almost a month ago. I'm a stay at home mom and have a 15 month old baby. he wouldn't sleep with me or talk to me, even sometimes wouldn't eat what i would cook. it got so bad that he would yell at me and made me feel so stupid, i would ask him what was wrong he would say we are fine. i thought I'll give him some space and maybe he will talk to me or something. we haven't gone out for almost 2 years on a date and every time i would tell him i wanted too go out on a date with him he would say i wanna stay aft home watch movies all day but he would do the every weekend! My family or his family would invite us to cook outs and he never wanted to go because he don't like them. he would say go out with your friends but i wanted to out worth him. we got into several arguments about it but this last time it got bad! he told me that he was acting like that because that sometimes i wouldn't fully clean the house or iron the close that i seem tired all the time. he said that sometimes he has to wake upin the nights with the baby and he works. i told him sometimes i wouldn't fully clean because i want feeling good i skulls vomit almost all day but he said i exaggerated. i told him i stayed not waking up in thenights anymore because i take care of her all day and night ever since she was born i thought it was only fair that he would start skiing it now. he never offered to help with her. during the day or night, and i never complained but now that its him waking up he don't like it. i told him got want me to do everything to keep you happy but yet i don't anything in return. i stay all day at home i only go to the store or tho my parents house to visit and I'm tired of it. so i moved out. i been looking for a job. i feel like i need to pick my self up. now he is asking me to go back he said that he will do anything you have his family back. i asked him for us to go to counseling but he said it's expensive. I'm just afraid of having to go through this again. what if he dont change? this is not the first time we go through this. at the same time i do wanna go back but I'm scared and tired of this. i just don'tknow what to do! any advice? sorry about long post but i realty appreciate any advice.
