Overreacting or he was an ass

So I work at a restaurant and of course I have regulars but this one regular has a crush on me. I know because he once asked for my number not only did he asked but he called up to the restaurant after he left to ask me told him. No I'm taken, So today I was taking one customer phone order and my coworker told me the phone was for me. So I picked up the phone and it was him and he was like he rather me take my order and every time he comes to pick up his food he always give me this look and makes me feel uncomfortable so I told my coworkers and they said that they will try to give him his orders although they don't really handle the take out but I do. So I told my bf about how the customer makes me feel uncomfortable and he told me just tell him to back off so I said okay say he does but just seeing him in general makes me feel uncomfortable. He goes to say that I need to start being like other women and start being mean and that's why guys keep hitting on me because I'm nice.I told him no once I tell a guy I have a bf they leave me alone on or if I have to constantly see them they don't make me feel awkward because I had a coworker who liked me until he found out I was taken. My bf also goes to say that other people goes through that and I just should deal with it. So I started crying and getting pissed and he was telling me I'm getting worked up for no reason but I told him he saying that I should just deal a with man making me feel uncomfortable. Thank God one of my male co-workers saw how uncomfortable I looked earlier and he is willing to deal with the customer if he ever be around when the customer order.

I felt like my bf was being an ass but I could be wrong and just being dramatic but when he said that just ticked me off

Thanks for the opinions everyone, I figured I was being a little over sensitive about and for the person who said get a grip about me crying. I wasn't at work crying I waited until we both was off work to talk about it like we normally talk about our day and it does be short thank you for calling blank how can I help you, then he'll tell me order I'll tell him the price and long it'll take. Nothing more I say to him his vibe just creeps me out and how he looks at me especially when he looks like he can be around my dad age which my dad is 50 but still thanks for the opinions
