I have been with my fiancee for five years, but we have only recently become engaged. In all of the time that we have been dating, his ex-wife has never expressed any concerns about me with the kids, but recently has become "concerned" that I am "cruel" to their 13 year old son. Now of course, the 13 year old is a typical, moody adolescent and he doesn't like much right now, including me. While, I understand this, she does not and is saying some hurtful things right now that are making me angry. Any advice on how to deal with her and with the teen without making things worse?
