WOULD YOU BE UPSET IF YOUR BF DID THIS?

On New Years Eve I was hanging out with a group of my BF of 5 years friends.. He was upstairs and came down a few minutes before midnight. Later he asked me to get his phone. I saw he had text a girl he works with five time throughout the day... she never even answered him. The text that upset me was at 11:55 pm saying "Nikki I f'n love you.. you're the sh*t city girl" .. because she works in the soho store of an eyeglass shop he works for. It bothers me still... what do you think? Note.. he didn't text ANYONE else on New years eve
