So this could be a long story! Basically because of various issues we; DH, myself and our DD1 and DD2 have not spoken to my SIL for over 4 years. When I say we, it was actually her that stopped talking to us just after our DD2 turned 1. Contact completely stopped and our children have not seen each other since this point. We have during this time sent cards to her 3 children for birthdays/Christmas etc and our children have never received anything in return. When her DD1 turned 16 (I thought it was appropriate to wait until she was this age) I wrote to her saying how much we missed her, how that none of this situation was her fault and that we wished her all the best in her gcse's etc and this resulted in a visit between us all (suggested and arranged by me - transport for SIL's DD1 facilitated by SIL and DH's mother). This apparently went well, however we have had no contact since and no recognition of our children has taken place. We took this as sad but a sign that we should move on and have not attempted to arrange anything further either although we did send a birthday card. So, in two weeks it is our niece's 18th birthday and I want to know if we should send her something or not? We were so close to this child from birth until she was 13/14 and it breaks my heart that things are the way they are. My DH probably hasn't even remembered it's her birthday and I know that anything we do will not be acknowledged - we also don't actually have her address as they moved without telling us so we will need to send it to her grandmothers. Will I be making things worse for her? Does she even care as an 18 year old?! Should I get her something or is it time to let things go?
