Need advice...

This might be long, but I’ll try to keep it short...

I’m not sure what to do. I love my husband. We’ve been married for 3 years, and together for 11 total. But his anger and attitude lately are becoming too much. And I try to talk to him about it but he apologizes and then a day or 2 later it’s back to the way it was. I am so emotionally drained. We have 2 children, 6 & 2 (girls), I work full time, 3 days a week, out of the house. He works full time, 5 days a week from home, with both girls. Our 2 year old is a handful, she has a severe speech delay, so only says mama and no and cries and whines a lot. Our 6 year old can take care of herself, but wants to play all the time. I am so exhausted from work, I have been falling asleep on the couch at like 9pm. I get our youngest to sleep first. And our oldest is usually relaxing with a movie. He says I’m doing it intentionally. So I don’t have to sleep in bed with him. Last night, he was very mad about it. Woke me up, demanded to know who I was waiting for, why I wasn’t going to bed. And said he doesn’t know who I talk to, I hide my social media..I don’t. I only have Instagram, and this if it counts. And my Instagram is just family members and a few close friends. He basically accuses me of cheating on a daily basis. I never want to have sex because his comments and attitude are such a turn off. Then if I ask him for help around the house or with the kids, he throws a tantrum and acts like I never do anything around the house. When I’m the one that does laundry, I cook and clean...sometimes I just need him to help the kids when I’m busy doing something. And when he gets in these moods, every little thing pisses him off. A toy on the table or a cup I was using that I didn’t put away fast enough. And then he makes me feel like everything is my fault! I must be cheating because I never want to have sex. Ugh!! Somebody please give me advice.
