Your question is the wrong way round. The concept of gravity being the force that makes apples fall is ancient. Before Newton, we knew that gravity makes the apple fall, but we didn't know what held the earth, moon and sun in a stable system.

What Newton did was to extend idea of gravity to the heavens. He did this by realising, and then mathematically proving, that the thing making apples fall is the same thing that holds the sun, moon and earth in a system.

This is what it was called 'universal gravitation'.

That's the neat part - they won't.

Popcorn moment!

The faster China progress, the more funding NASA and SpaceX will get to keep the US ahead.

I've always cheered for the Chinese space agency for this reason, and I always will.

Proves my point ;)

Is that he doesn't like the specific word 'Daddy' or that he doesn't like being dominant?

Because if it's the former, you just need to find a word that pushes your buttons, but he's OK with. Try Sir, Master, Captain, Commander, Your Majesty, Doctor. Whatever.

He its dominance he's not OK with, then that really points to sexual incompatibility.

Will anything good come of your telling your GF? It'll cause a rift between your GF and her parents, and it will cause a rift between her parents and you. Any fallout, and her parents will likely work to undermine your relationship with her. I can only see bad outcomes of you telling your GF this, and no good ones at all.

What you do is up to you. I've always lived my life with the philosophy that we should stay out of other people's business. This sub vehemently disagrees with that, and will urge you to tell your mother, but I would caution otherwise. Your parents relationship is their own, and it's for them to work through their lives.

If I found one of my friends or family was cheating, I would take it to the grave with me.

He clearly has a preference for your ethnicity, but if he's been with you for 2 years, it sounds like it's working out.

Its OK to have a preference.

If your parents don't share a room, its sounds like they 'broke up' long ago, but they stay together as they are partners in life if not in sex.

I'll tell you a cautionary tale OP. A teenage girl posted on this sub many months ago, having found out her father was cheating and asked what she should do. Everyone on this sub urged her to tell the mother.

A few days later, the girl posted at update, saying she'd told her mother, but it didn't go well. Her mother resented her for telling an uncomfortable truth, her father had disowned her, and she was distraught at the chaos her intervention had caused. She wrote many paragraphs about how much she regretted being the catalyst that destroyed her family, and that she wished she'd never taken the advice of the sub. And predictably, everyone on this sub downvoted her into oblivion.

Siblings can be very competitive. My own mother is one of 4 daughters, and they all constantly compare the successes of their children's looks/salaries/relationships with each other. It's kind of sad, but that's just life.

It sounds like your mum has that kind of relationship with her sister, and your aunt has been crowing that her own daughter has a BF worth showing off and your mum has ended up feeling jealous. Again, it's pretty sad.

You do you. You don't have to justify your choices for your mothers gratification.
