Make Guidelines

The longer you are in a relationship the harder it is to get out, even when it starts to turn negative. Don't make being truely in love mean being in a bad relationship.
Taking abuse of any kind does not prove you truely love someone it just means you do not love yourself. If you don't love yourself you can't really love anyone.
After all the stories and cute stuff wears off it is just going to be boring you and boring them. Make sure that you are ok with that.
