This is tricky, jean17. Your ex seems to be sending mixed messages, and maybe your sister is trying to protect you from being hurt again. You are right - if your ex is not to be in your life any more, he really can't bring you flowers - but I understand you feeling guilty when he does. I think though it might be best if you can somehow tell your sister, since she is likely to find out anyway and will be more upset if she thinks you were hiding it from her. After all, it is not as if you asked for flowers. Maybe if you say first that you know she will be upset but you want her to understand.. she might be gentler and not come down on you so hard. Seems your sister has your best interest, and family is really important, if we can keep in good with them.
