My boyfriend wants to go out with a friend. They are going to the friends family members house and spending the night.

I don’t personally agree with this. If he wants a guys night of course go out but you come home at the end of the night. He says it’s no big deal. I have two other kids from a previous relationship that he helps with day in and out and I am currently pregnant with his child. This is his first serious living together relationship. I think we just aren’t seeing eye to eye because he is like young adults (25) can have sleepovers. I think that once you’re committed with kids etc you don’t do that anymore. You end the night with your significant other.

What is your take? Am I being unreasonable?
