Is it normal?

My bf and I have been together for 5 years, living together for 4 of those. I have gone on business trips or gone away for family stuff and so has he. So we have definitely had our time apart.

Normally we are constantly texting and calling eachother saying how much we miss one another. Called eachother before bed every night!

He’s been away for 4 days now for a business and niether one of us has said we missed eachother. It’s not that I enjoy him being gone but it’s like eh, I’ll see you next week.

Is this just a normal, we’ve been together so long kinda thing? Or is it a bad sign. I honestly feel kinda guilt for not!

Please don’t be mean:)
