I'm 9mo pregnant with a toddler. Since I got married, my husband has always spent at least 3 evenings a week out from 5-6pm to 9.30-10pm (although it's frequently later). These past few weeks, he's been out moreso, 4-6 evenings a week. These outings are all with his teenage son (from a previous marriage) doing sports or mosque gatherings. A few times a year they'd stay over at the mosque also. He also travelled with his son last summer and left me pregnant at home alone for 3 weeks. We'd been married a few months.
It bothered me a lot as a newly wed and I have communicated this with him but nothing changed. When I had my first child, nothing changed. When I fell pregnant again nothing changed. I've been struggled with the pregnancy and handling the toddler but my husband doesn't really seem bothered. Yesterday I had a nasty fall while they were out in the evening and had to go go maternity triage. My husband came home to put the toddler to bed while I went to the hospital. They told me I'd need to come back this morning for further tests. Husband and his son had football this morning and decided that was more important than taking to the hospital. So they went, and I had to wait for them to come back to watch the toddler so I could go to the hospital this afternoon (hours later than I was told).
This has made me desperately unhappy, but husband doesn't see it. He thinks I have unreasonable expectations of him/family life and resents me for suggesting he's not fulfilling his responsibilities as a husband/father.
What exactly can I do?
