R/AskMen, What are your most important tips and advice for a healthy relationship with a gf, spouse, or Significant Other?

For myself, I think the biggest tip I have and can give, even though I'm younger (mid 20s), is that I always try to learn more about how I can improve my relationship.
I'm always reading and trying make myself a better partner whether it's through sex or communication. I make an effort to improve myself or the quality of the relationship. Stagnation and just doing things the same all the time is the game ender in my opinion.

I don't think reading anything improves a relationship. If you have trust, open communication, love, strive to show the other they are your one and only, and put the other before yourself, that's what makes for a good relationship in my opinion.
