How can I create new relationships with my siblings now that we're adults?

Have you got any common interest that you can talk about so you have something that you both enjoy doing

Well It's not hard , After all you're all Siblings , You can invite them to your place at special events or holidays , Ex : Christmas , Thanks giving.. Or go to movies or do something fun , It's always easy with Siblings.

Try to find an activity that the both of you enjoy. If that's tricky you can always try a new activity that the both of you can learn together!

By being honest and open with them, and by treating them as if they are your friend. Regularly chatting with them, or acknowledging their experiences helps create a stable sibling-relationship.

Trying and growing up with siblings and wanting to keep a mutual friendship can be hard, I know right now since my sister moved out about three years ago there's been a little bit of some 'tension' between our friendship. Sometimes all you'll ever be with your siblings is blood or non-blood relatives. You can't have what people have in tv shows or movies where they're close with their siblings, some people can pull it off and others can't and just stay the way they are. I don't know how to really help let alone give much advice, but I don't think you'll have much to worry. They will always be there for you and help you out and just be your sibling no matter what.

I would recommend, from my experience, meeting in intervals for an activity you both like i.e. holidays or drinks or camping etc. and discuss your lives. You can also try ping-pong conversation and staying in touch over platforms like facebook, whatsapp etc. :)

I do not feel you can create a "NEW" relationship with someone you have a previous relationship with. Rather, I feel it best to ask yourself how and why might I choose to change said pre-existing relationship. Being adults, perhaps there are topics that have gone previously undiscussed that may add value to the both of your lives if you both take the time as adults to converse about / address them.

Find common interests and talk about your aspirations now that you are both adults and everything will fall into place, but also try not to loose the fun side you had when you we’re younger, your concern suggests that you had a great bond and that’s what you are afraid to loose, trace back to when you first noticed the strength of the bond and draw from that and carry that over into your adult life and you will see that just because you have matured as individuals the bond you have will always be from when you were children!
