Boundaries in Marriage - Need Advice

Salam. I’m a convert. Most of us grow up in cultures that see marriage very differently from those born Muslim, and I’m struggling with that clash right now. My husband, who is Muslim and raised in a Muslim family, has gone away on a long trip with friends for a few weeks and left me at home. At first I didn’t mind, but now I’m anxious all day. I live far from my family, can’t visit, I’m working, and I haven’t told anyone that I’m alone - my parents and friends don’t know he’s gone. Where I’m from, and especially my dad’s view, a husband and wife do things together and don’t leave each other behind; holidays and quality time are meant to be shared. If I tell them, I know it will create a lot of tension. My mum would probably be even angrier than my dad and both might say, “this is how Muslim men are, we told you so.” In my husband’s family this is apparently normal, and I was told not to cause trouble and to let him enjoy himself - don’t contact him unless necessary. I was a bit shocked when I heard that. This isn’t the first time he’s gone away like this; the first time it caused big problems with my parents when I was physically with them and couldn’t avoid their snarky comments. Even if they didn’t show it later, I felt their feelings. So I’m lost and would welcome advice: would you tell your parents so you have moral support but risk family tension, or stay silent and just get through the next few weeks? What would you do if you were in my shoes? JazakAllah khair for any thoughts.
