I had no problem with my exhusband and his son's siblings. There was a big age differenct like 10 years between my stepson and his little brother, BUT his cousin who was 18 months younger than him always tagged along and my ex had no problem with the other little boy. He spent the night, went to church and my ex did for him like he did for his son. The cousin's father was involved and did for my stepson, so no problems in out household. ie their mother's were sisters.
We were married, that is different than dating in my book.
