In relationships, there are five basic rules that apply to a fair number of things. I got this list from
1. Don't be a jerk. If you want to be a jerk, go ahead and do it. You'll probably make it worse as far as your relationship goes, so don't do it.
2. Be honest and consistent in your behavior. If you keep saying the same thing over and over again, eventually your partner will get sick of hearing it and move on to something else.
3. Make time for each other in your schedule if you have one, but don't overdo it! If you spend all day with your partners every day, after a while you will start feeling bad about yourself if you have nothing to do for an extended period of time and may even start seeing other people because you feel guilty about leaving them all day every day!
4. Don't pressure your partner into doing things they aren't comfortable with (for example, even though they love traveling, they often won't want to take trips with someone they don't know well). They might also not enjoy being in a relationship that isn't the same kind of family, so the risk-benefit ratio isn’t great here either (they may not be interested in spending the rest of their lives with someone who doesn’t have traditional family values).
5. Make sure you give each other space when necessary (even if this means honoring boundaries more than usual), but try to be reasonable about it because there is no need for perfection or rules when the relationship works so well without them!
