hello everyone....quick backstory... My uncle2 has been married for 34 years and has 5 children with his wife. 16 years ago he had a 3 month long affair which resulted in him having a "lovechild" with this other woman. Everything was kept a secret from the family and his wife. The affair ended but he always looked after his son, paid child support, bought clothes, had regular secret visits with his son and generally always kept in touch with his boy.
So 2 years ago, everything was been revelaed i.e the affair which happened and the birth of his son as a result, my aunt obviously left my uncle and they are currently separated and in the process of a divorce. My cousin's stopped speaking to their dad for some time when they found out what had happened and have a difficult time accepting their recently known half brother. As of now my uncle and his wife of 34 years are on semi-good speaking terms and my cousins have starting to speak to their dad again.
Now.....his "mistress/woman had had son with" is now known to the whole family, we've never met her in person BUT other aunties are now saying me and the rest of the family should welcome her, and speak to her every now and again. e.g it was her birthday a few weeks ago and my mum asked whether I had sent her a message to say happy birthday (which i didn't) as I don't feel i have too. another example is sadly her father died a few months ago (which is very sad for anyone) and again I was told i should contact her and send her a message of condolence. I didn't because as far as I am concerned...she's a woman who had an affair with my married uncle 16 years ago...thats it... I've never met her and probable never will as she doesn't even live in this country. So my question is AIBU to just not necessarily have contact with her and just live my life as i always have been, I really don't see why I'm now supposed to treat her like shes my new aunt just because she had a lovechild with my uncle?
