I need your opinion pls!

So today my husband forgot his phone. My daughter was playing with his phone and she gives it to me and i look and its in this message he had of some girl saying " if i stare when you stand next to me will you feel awkward?😉" ( my husband is supervisor of call center so yeah) and he responded "lol". Few min later he comes back for his phone and i showed him the message and he said that it's just a girl that works there that is nothing and we started arguing. He said im blowing it out of proportion but i feel disrespect, he could have stopped her but instead he just said " lol". By him responding that what does it mean? If i make sence. Im so mad and sad and confused ill appreciate your opinions!
