Always Remember:

1. kissing can and will, get boring.
   
2. its ok to go to sleep on opposite sides.
   
3. forgetting favorites, dates and replies is only human.
4. you dont have to like, or be friends with all of their friends and vice-versa.
5. they have a right to spend weekends dedicating to their friends and family. you have the same right.
6. privacy is still in play.
7. trying simple things that they like, no matter how much you are sure you will dislike it, is a very small step you can take to show your love to them.
8. you dont gotta have the same taste in music, food, books etc.
9. saying i love you, thank you, take care, please and i missed you really helps.
10. you cant agree with all their life decisions and they cant with yours. keeping an open mind and having an honest and deep discussion about it helps. 
11. they dont need your permission to do things and neither you need theirs.
12. the intention and care behind the gift matters. not its price tag. 
13. dont try and change them. help them become better versions of themselves and get the same help and support and care from them. 
14. know what matters most and focus on that.
