Work Conduct turned PERSONAL?

My co-worker brought her 20 Yr old son to wk with her..I sd hello, nice to meet you and the office had a social conversation about dating and kids in this society (I wk with juveniles) So its a common problem.Anyways, later that evening, my co-workers son "text" mess me "Hows it going sweet cheeks?" My hubby was furious thinking I gave him my number which I understand his Point of View, I wld be worse if tables were turned BUT all this could of been avoided if my co-worker had kept tabs on her ph. Come to find out, She gave her son my number to just "mess around with me" She came across like it was harmless fun..BOY was she wrong, what should I do????? My hubby wont speak a word to me or even hear me out, he ignored my BDAY and Mothers day over this, completley ruined my week!!
