Love yourself before you get into a relationship.
Know yourself before you get into a relationship.
Accept that we are all flawed and no one is beyond reproach.
Always speak with "I feel" instead of "you do".
Never lie... EVER. No "white lies" no "fibs" and no "liberties with the truth" or "bending". Be absolutely honest with your partner, always. No negotiation
Love like its the first time. Don't make your partner pay for your past hurts. If you can't, then go back to lines 1 and 2
Say "I'm sorry", then figure out a plan to fix it, then follow through
Keep your promises!
Concentrate on each other's good qualities, but work together on how to improve on each other's weaknesses
Spend time together, QUALITY time in which you both interact. This does NOT include watching TV together.
Exercise together. Keep each other active and healthy
Support each other, emotionally, physically, mentally, etc.
Have lots of sex, even when you don't feel in the mood. If you aren't in the mood a lot, find out why not and work on it. Sex is VERY important as it often acts as a bonding agent between mates.
Tell stories to each other, personal ones.
Encourage each other
Remind each other how proud you are of the other
Discuss all the big decisions together, and most of the smaller ones too. (the petty ones you can usually do without).
Don't raise your voice during arguments. The louder you WANT to scream, the quieter you SHOULD speak.
Live together as if you are trying to set an example for what relationships SHOULD be... because you are. Your children will look to you as an example, so be a good one!
