slightly confused but don't care

so my husband and I separated in January and I have completely moved out and we are both living happily away from eachother..well at least I am..he's got a girlfriend and her daughter living with him and I live with my sister and we share custody of my son. I was talking to a customer at work about stuff and they didn't flinch when I said he has a girlfriend but when I said I have a boyfriend they said I should get the divorce first before I get a boyfriend. is it just me or does that seem completely double standard. my son loves my boyfriend and his fathers girlfriend and we're all happy does it really matter I'm going to file for divorce within the next month why does it matter.
