You're both going to have to be willing to learn some good communication skills and there's some very good videos on that out there, by Carl Jung. No use being unhappy. If one has a short temper or lashes out before thinking, these things must be addressed. They won't go away.

Both of my long-term relationships have been with women that had personalities, interests, skills different than mine. I sought partners that would complement me in those areas; make us whole at a team (and I believe they did the same). So there was not much to handle. We appreciated what each of us brought to our partnership.

Tons.

He's extrovert, I'm introvert.
He has a child, I'm child free.
He grew up with money, I was poor.
He's got two degrees and a Masters, I have only a two year college education.
He's got a very close, supportive family, I have no one except for one brother in Tennessee.

At least we both have the same political leanings. I couldn't be with a Trumper. 🤮

Talk it out. Communication is the foundation of any relationship.

If something is bothering you, mention it. You both need to be in a mental space where you can bring things up, without the other being defensive or aggressive. If that happens, the relationship is already dead.

You don't have to agree with each other, but you do have to try and understand where you are both coming from.

Yes, a lot of differences.
Yes, a big impact on my happiness.
I don't handle it. I deal with it one day at a time.

Not only is it personal, it'd be a longer reply. I sent you a message. Maybe better to discuss there. Hope you'll reflect on why I said that.

No. Though I think my last relationship there were a lot of differences and, maybe it's just me but, it didn't end too well for me. Of course, this was about four years ago.

I was married for almost ten years before my wife left me. I'm not in a relationship now, but we had many differences and many similarities.

If It’s like that and conversation doesn’t help then I leave. Life is too short to be unhappy.

A couple does not have to agree on everything, but they must agree on a small number core values/principles.

If they don't agree on this handful of core values, then the sooner they part ways, the better they will be.

Am I ever! We were very set in our ways, pushing 40, different languages, different cultures, different continents, different national strategic alliances... same God though, which I credit as the equalizer

Our relationship has often been like one of those venn diagrams. I have my stuff, she has her stuff, we have our stuff.

Any relationship can be successful if you have the 3C's, Communication, Commitment and Compromise.

Remember your individual goal when joining. If you really need that relationship in a short term, suck it up, compromise.

Yes. Has its pros and cons.

Mostly, just smile and nod.
