Long story - I was adopted and in my twenties traced my birth mother. We saw a lot of each other in the first few months of meeting - she had no support at eighteen when she fell pregnant and my dad returned to his home country before she could tell him she was pregnant. She met her now husband a few years after she gave me up told him about me showed him photos of me he said I was a beautiful child and they never spoke again about me. They went on to have three boys who are now all late twenties early thirties. Over the years she made it quite clear she would never tell her husband and boys about me although her husband knew about my existence so it strained our relationship somewhAt and she stopped making efforts to meet me due to lack of transport, money even when I’d always offer to drive to her home place and meet so I haven’t seen her now in about 5 years or so just the odd text in birthdays. I’ve accepted that she’s not interest through counseling! However I have been thinking of her sons, my half brothers so much lately and not sure would it be an awful thing to contact them as I would love to meet them - as I said they don’t know of my existence - I can see them on Social Media and have even walked by one of them or should I leave well alone?
