Hi, I also have a half sis and bro they are younger than me, but I don’t have any contact with them I only saw them once when we we’re young, but as time passes I often wonder how are they doing or if they are well, I don’t have any opportunity to talk to them, I can’t even search them on Fb, I think what I am trying to say is there are gaps in between our lives, that would never be patched up with a few hi’s and hello’s or over a cup of coffee once a month, if you want a relationship with her, it would take time, You would take the time even if it’s just a coffee and sandwich, on your part if you genuinely want it just let her know that you are there for her even if she doesn’t want to have a relationship right now, It is good to know that someone cares and if you really do, just tell her that you just want to know if she’s okay and that if she needs any thing you are there for her, that’s it, Atleast she knows, and you have to be prepared to accept whatever outcome, if she reciprocate or not. That is love, we just give it our best even when we know is in vain... and we don’t give up on our family (half or full). 😍
