<human>: 28 [m] with 26 [f] together for a year and 2 months in LDR (We see eachother often though as she only lives 2 hours away)

Recently I've taken on a massive workload at my job and because of that I've been extremely tired. I don't really sleep much so it doesn't help on that behalf either. I get maybe 3 hours a night if i'm lucky.

A fairly prominent figure in my company came to our office this week so I've been dealing with impressing him and basically trying to work my ass off to make a good impression. A normal day goes, sleep 1 AM - 4 AM, get ready, drive at 5:30 in a 2 hour traffic jam, work 8-5, 2 hour traffic jam back. Recently I've been having to work at home aswell though.

Last night, I was on Skype with my S/O and I was getting extremely tired so I wanted to call it a night. As my S/O laid in bed she was telling me about her new cute panties and I told her they looked sexy on her, but didn't advance from that. About 5 minutes later I could tell something was bothering her, so I asked what. She went on to tell me she thinks I'm losing my sexual attraction for her and that she'd been trying to be seductive for me and give me signs that she wanted to play.

Now... me being on 2-3 hours of sleep and a stressful day I was too exhausted to register it in my brain when it was happening. She began crying saying she just wanted to be sexy for me and I tried re-assuring her loads but it didn't help. After a while she stopped crying and we went to sleep but I just spoke to her on the phone during a coffee break and she still sounds down.

Did I mess up? I explained to her I was exhausted and I just didn't register it and I was sorry, but it didn't help.

What do I do reddit?
