Would you be worried if your SO suddenly started dressing nicer for work?

He suddenly fixes his hair at least twice. Checks himself in the mirror a few times before leaving and then checks himself in the car. Puts on a lot of cologne, even on his dick and ass..suddenly he wants to wear the glasses I bought him as well, suddenly he wants his uniform ironed to perfection. Suddenly he comes home 30 mins to an hour late. Suddenly brushes teeth before work and takes in mints. Suddenly two new female names pop up when he talks.

Idk what to do. I just iron and cook and pack his lunch and send him on his way with love, I can’t help but thing he has something for them. I ask but he starts crying and says nothing is going on, sometimes he gets angry and is mean. He suddenly prefers porn over me.

Its not even killing me at this point...I feel nothing but confusion in my head.

What would you do?
