Is this bad manners

I went out for my 19 birthday ( December 11, 2014) and we were eating just me and the girls. And a man who must caught eye of my friend came over. They were hitting it off. And she left with him after our cake we finished. I was cool with it. Well they lasted 3 weeks until he too her virginity and left. About a week later we walk right into each other in Victoria Secret. I didn't care why but creepy. He starts to hit on me. Now I have my SO. he starts to touch me. And my mouth goes without filter. " if I wanted a vagina cleaner I would go to Smith's and pick up a douche!" My friend the same one came back with her purchase. And asked what was that about. I felt so bad I couldn't tell her what he had done.
