Dating

My Brother is dating a workaholic, how can they both be happy without feeling distant?

My Brother met a girl at speed dating, they hit it off instantly and are in their 30’s. He asked for her number and she gave it, and then she said let’s meet for coffee. They texted a day or two before he invited her on a date.
At first she declined the date saying she had no time on weekdays it must be on weekends, and explained because of her job hours. He said ok and made plans for the weekend. She replied “I’ll have to see if that works for me”. They text daily to stay in contact.
Her job is caring for disabled children, she goes to school with them on weekdays full time job to care for medical needs, and sometimes after school or weekends does home care as a part time job. My brother sees nothing wrong with her working and she is very dedicated. Here are the issues he is concerned over:

1- She seems to take her job over keeping plans with him, he has yet to see her since they met. She makes her own weekend schedule and could change hours to see him for a short date.
2- When they text she rarely asks about his day, mostly she talks about her job.
3- One of the children she goes to the home of has a single dad who is 45 and she talks about how nice this man is to my brother in their texts and that she is friends with him. He feels like she might be crushing on the dad and not interested in him.
4- My brother is almost 40. Him and this girl briefly mentioned wanting kids. She said she’s in no rush. At almost 40 my brother had hoped maybe in two years to be a dad he feels too old to wait longer. With her job he feels like she won’t settle to ever have kids.
