Disclaimer, I'm fairly young and thus inexperienced, but I'm looking for any insight or advice you can provide.

I am the last male of my family bloodline. I have no desire to waste my time and money on women, let alone marry and have children, yet I feel inherently guilty for the dissapointment this will bring to my family. Our name won't be passed down (unless my sisters feel "empowered" enough to keep their own name in marriage). I haven't been explicitly pressured by anyone to get married, yet this will most definitely come up sometime. I also don't want to put this kind of pain in my grandfather's life during his final years.

I'd love to say I'm MGTOW through and through, but I just can't seem to put aside the wishes of others completely. Maybe it's weakness on my part, or something else, but it's nagged me more than women themselves recently. Any advice or support would be greatly appreciated. Thank you.
