Should I lie to my girlfriend about my vote?

Politics is something personal which should not be mixed with family affair .Your answer "private" is the best .It avoided a break up . 

I'm not surprised that decent woman wants nothing to do with a Trump supporter.  He is a liar, a racist, a traitor who tried to overthrow the US government.  He fooled millions of people into believing the election was stolen.  He lies twenty times per day, led you to believe he was a good businessman when his is the most spectacularly failed businessman in American history.  He boasts of grabbing pussy and has cheated his way through life.  He hires hookers like Stormy Daniels in the month after his son was born.  If I was your wife I would dump you immediately. 

Grow a pair! Tell her who you voted for and let her know you'd do it again if he runs in 2024. If she dumps you, she's not worth it. Be a man.

A relationship based on lies is a relationship that has already failed.  When/if she learns you really voted for Trump she will be entitled to regard you as being as big a liar as Trump.  That you find being opposed to systemic racism is a negative, and your family apparently approves white privilege certainly assures a nasty break up if she has to discover all this.

If she'd break up with you over voting for Trump, then you shouldn't trust her to stay with you through thick and thin. It'll suck at first, but it's a much better alternative than staying with someone who will love you or hate you based on a political vote. Sounds like you can't really be yourself around her anyways.

Good luck, brother.

You don't have a girlfriend. You have Asperger's instead.

Well find a new girlfriend that's ok with your own personal political views

I have a feeling you already know the answer to this.  If a new relationship starts off with lies, it has nowhere to go but further down.  Also, if she threatened to break it off based on your political beliefs, why didn't you take her up on that?  Not only does she hold very strong opinions, but your beliefs are so odious to her that she'd toss you to the curb.  Why are you still with her?  

Lying becomes a habit.  Lie about one thing, you'll lie about another.  And another.  And another.  And then pretty soon, you're lying about everything.  Then again, you voted for someone who has spent his entire life lying, so there's that (seriously; he lies about EVERYTHING).  But maybe you're some American Republican who will always vote a straight Republican ticket no matter what (I'm a Canadian who leans left on some issues and right on others; honestly I wish you lot would get your collective s*** together so we might consider re-opening our southern border but right now we can't risk it), and you don't really care how bad the Republican is or how good the other candidate(s) are.  But we digress.

I'm not really sure why 'retweeting black women' is a such a big deal for you (this is what's known as a tell), but I'm sure you have your reasons.  I'd ask why you (as a Trump conservative) would want to be with someone whose views are opposite of yours, and why you can't tell the truth about something simple.  It's almost like you (like most Trump voters) don't want to face the consequences of your actions so you lie about it.  In this case, losing a relationship.  But you bought the ticket, so now you get to take the ride.  Own up to it, and if she dumps you then that's that.  Suggestion?  There are online dating sites that cater to conservatives.  Become a member.  It's likely a better dating pool "for you" and where you'll meet someone who shares your views and values.

Either your GF took your balls and ran them down the garage disposal, or she is insanely hot and has real orgasms...
