My Husband's Brother

I married at 18 and we had a great life together, then on very cold snowy day. My husband was killed on the highway in in a multi-vehicle accident, he was caught in the middle and had no chance. That left me with 2 small children to raise by myself, my parents were already deceased by the time of the accident and I've no siblings. My husbands were already retired and in a retirement village and helped as best they could. My husband's brother and only sibling was overseas working and returned soon after the accident. He is the older by 4 years and single, great job and so he bought a house and had me and my children move in with him. I was to look after the house, he would see we were okay. With was great for me and the children, then the pandemic struck, we were together in the house all the time. He was able to work from home and us being together all the time. We ended up in bed together and as a result I got pregnant and after the lockdown we married. I had a son and for him and we're quite happy together with the 3 children and I'm now pregnant again.
