What should i do Help!!( long story)

I will try my best to make it short.I am 26 years old. I am married 3 years now but we are 10 years together. We have 2 boys. 3 and 1 .

So my story starts 4 years ago when i got pregnant with my first. My husband's mom came to leave with us she wanted to help. (Terrible mistake).. A few months into this problems started. Everything i was doing and everything i was saying was wrong and she made sure to tell him when he cames home from work .. As you imagine we were fighting and a distance between him and me grew. It looked to me he was taking her side because he was trying to change me. I was sad and angry and especially after my son's birth things got the downfall. She stayed for 1 year after my son's birth as well but believe me i regret every minute of that time i reached the lowest point of my life.no support of him he was verbally abusing me.So as you imagine my husband and i let her create this hole between us. After 4 months of my mother-in-law leaving got pregnant with our second( to mention here that i was starting considering divorce but baby number 2 came)but i said lets try... make this work.. the 9 months of me being pregnant was really difficult as i was constantly tired and working and raising a 1.5 year old no support but at least i didn't have mean comments from him..finally baby arrived and the first month i saw no support of my husband as i was hoping.a month on with second baby we went for holidays back in our country and finally i had some help .. the time came to leave and my husband decided on the airport to stay there instead so i left by myself and the 2 boys .. a month later he decided that he wants to be with us and he really wants to try things out.(well i let him come back). the last year is the best year that we had in a long time.. he helps around the house. Helps with the boys.. doesn't complain if something is not done..and. lets me take a nap after a long day.. so all sound great but i am missing something.. something is gone . I don't have the attraction for him that i had.. i don't want to have sex with him i am never in the mood.. even though we have sex is more like a chore to me. Don't take me wrong i love him but something is gone.. he knows and try a lot but almost everyday i wake up thinking maybe i should ask for divorce..but i never take a decision thinking the years being together the two boys that we have. Is it something wrong with me? What should i do? Do i live like this the rest of my life wondering if i should be with him!?
