My relationship

Hi i am 22 years old with a 4 year old boy and a 4 month old girl. I am married to a 30 year old man and he isnt the nicest person but i love him and i think i am going crazy but i want to have another child already i mean i come from a family of 9 kids and all my siblings have kids and i love being pregnant. I wanted to become a seraget mother but my husband said no ones baby will be inside of me other than his but he is telling me he got his pare and doesnt want more. When we got together i told him i wanted at least 4 kids and he said yes and now it is changing and he is not acting the same. He has been "working" alot more than usual. Not coming home right after work. Not answering my texts like he used to and not wanting to have sex as offen as he used to. We used to have sex every 2 days now i am lucky if we do it 1 a month i am worried that i might be losing my huaband to another person.

This is my family i love them to death
