My partner has three adult daughters, all in their 30's. Long, long, long story short, he and I have been together for 12 years, their mother passed away a year before he started dating me, and the daughters have completely refused to accepted our union. I am quite a bit younger than him, but have been nothing but a committed partner to him, and fully intend to stay with him for life. There is the eldest daughter, and two younger twins.
