This is Psychlady. You never have to do nothing when it comes to resolving conflict. You only have to accept that their response is not within your control. I would make quite an effort to make peace with your sister. You can only do that by finding a way to offer an apology that will be special to her. It is difficult not knowing her but you will at least be taken notice of if you offer an apology in a way that will melt her heart. If she is not receptive then you know she is not open to this yet. Sometimes making an apology after giving the other person some time is more effective. Sitting back may be taken as accepting the situation and that is not the way to resolve anything. Instead be proactive and show her that you are able to apologize and you miss the relationship you had with her.
Please press excellent service if I have helped you
Hi Cathy (hope you get this and not a different expert)
Thankyou again for you input, I will write the letter and do it with compassion and great thought. Now, my mother is treating me like a doormat but that's another story in itself. I think it's because I have always been there for her and she uses me to vent her frustrations as my dad has alhzheimers so he's not there for her anymore. I really need to learn how to be assertive I guess. I will let you know how things turn out..Clou :)
