Honestly, I'd waiting on responding here. I sorta hoped that there would be more people to chime in and be able to say things in a better way. I tend to be kinda blunt.

Basically, you don't need a Master that would treat you that way. Age shouldn't be a factor for you at all. There are people in this community in all age brackets. In any relationship, BDSM or vanilla, your family is of the utmost importance. Any Master that would ask me to choose them over my family, wouldn't be my Master.

Personally that guy sounds kinda like a shit head to me. No one should treat another person so poorly. You deserve someone who will respect you, and your wishes. At this moment you wish to spend what time you have left with your mother. You should. Once she is gone, you can't have her back. There are other men, and other Masters. But, a Master that isn't willing to take your feelings into consideration... well, really isn't worth your time.

Submissive or not, you have feelings, and they should be respected. Especially for something so huge. "I want new shoes" and "I want to spend time with my ailing mother" are VERY different requests. One can be dismissed, the other can't.

I know it's hard for you, and any break up is painful. But, you will be ok. You will find someone else, and you can still be happy. I hope all the best in the world for you.
