I don't think I will be able to attend his graduation sadly:( Should I break up with him or what?

In a healthy relationship neither party has "control" of it. But as his parents raised him and likely paid for his degree their wishes re: the graduation are paramount to yours (someone who's only been in the picture for less than a year). If you care to hang out and see if things get better you're certainly within your rights to do so. This guy will be out from under his parents' financial control once he gets a job and that may affect his ability to stand up to them vis-a-vis you. But when a guy's parents don't like you it's worth asking yourself why. There may be some things you need to change about yourself.

Many things in Life won't be fair. This one is a "small one" compare to the things that follow. Most people get into a relationship for

Companionship. LONG DISTANCE robs you of that.

When you feel the loneliness, you feel the difference.

As for the approval of parents or family...

I’m Mexican. She is White and Strawberry Blonde

My Ex Gf, once overheard that my brothers and sisters, didn't like her. 

She told me about it and I confirmed SHE WAS RIGHT... 

they don't like You. 

I told her "They don't like you, SO I FORBID YOU TO DATE THEM!!" 

She said "WHAT??!!!" I smiled and reminded her, that 

HER RELATIONSHIP IS WITH ME. 

As long as we are okay with each other... "F" the world. 

My Mom adored her and My Dad really really enjoyed her company and silliness. 

Interesting that, that didn’t bother her, only the negative. 

When her friends met me, they didn't like me either. 

Months later, none of her friends were with their "then BFs" or even close friend with each other. 

Her and I were still strong for about 3 more years. 

If you let others dictate your HAPPINESS, You're A Puppet. 

Stick with the happiness you have with your mate. 

One day, your friends will Admire and Respect the choice you made. 

If they don't... So what!!!, YOU WERE/ARE STILL HAPPY. 

So... "F" the world. 

When my friends or family get NEGATIVE about a mate I'm with, I agree with them and BLOW UP the situation or issue they bring up. Then I throw in, HOW AMAZING THE SEX IS with her and that is why I allow her "flaws" in My Life.  

Usually BEFORE I go into the details of how great she is... THEY DON'T WANT TO HEAR ANYMORE. (sex talk bothers my family AND I KNOW IT, so they drop their comments) The sex stories come from a Porn video I remember and all are LIES, but it shocks them and 

they F-Off. 

You could have FUN with something like this.

I DID.

High school graduation? Don't fly across country. College graduation? If that is the case, what is "not fair" is you continuing to be more invested in his parent's attitude than HIS! Don't go if you don't want to but it could be that you are too young to be putting yourself in this position. Really.

The only thing you have control over is yourself. If his parents have more control "over this relationship" than you have over yourself? Break up. Otherwise? If you don't WANT to break up then you don't mention a real reason to do so.

Go with how YOU feel and not what you're parents think is best for you. Its your life, not theirs.
