BM the last year or so has been leaving SS13 in charge of SD10 and SS6 on their days off from school while she works, or when she goes out wine tasting. So about 2 weeks ago SS6 comes to me and tells me SS13 has been hitting him and picking on him when BM leaves them alone. SS6 is a liar... almost without control, like he really believes the lies. But i stuck behind him on it and told him he can call me anytime and gave him my cell #. Since then he has called almost every day and i have no problem with that except for feeling guilty that he calls me to talk but doesn't call BF.
