Why am I being mean to him?

Jade • Amalia Aya Durand.... 18.08.19 💕😍💕

I've been in a long distance relationship for 2 years almost.

We see each other every 6 weeks or so but he's moving here in 2 weeks. He proposed in March and we also decided to start TTC. Since then we always plan visits around ovulation but no joy yet.

Anyway he left 5 days ago and since he left I feel different. I am anxious over nothing, I'm not replying to him like I was and when we have spoken I can't even paste on a smile. I truly love him and I'm trying to snap out of it but I just have all this anxiety building inside myself for no reason. He's asked what is wrong but I don't know what to say because I'm being irrational.

I thought it may be AF but it's unlikely as I still have 11 days to go and never feel any indication this far ahead.

Which means it's me... but Why?
