BE AN OPEN BOOK
Be as open as possible with your partner, say what it is, when it happens and exactly how it feels or affects you. Your partner is meant to be your best friend, no secrets should exist between you two, especially if it has to do with your feelings about him/her or the relationship.
It is easy to overlook mentioning some things because you feel "it's not that important", and that thing you feel is not important could be affecting your attitude towards your partner and the relationship. Every little thing should be said and talked about, that is how bonds form and are strengthened. Your partner shouldn't struggle trying to figure out what is going on with you. Make them feel like what they are, your partner, your team mate.
LITTLE GESTURES
It is important to do those little things that show your partner that you are aware of their needs and will always be there to help. It doesn't have to be something extravagant, small acts of service like helping with some errands, a massage after a long day at work, offering to make/get a meal.
Little gestures that pertain to what your partner likes/enjoys will also go a long way, if they love chocolates, surprise them with some chocolate once in a while, or get their favorite meal or a little gift in their favorite color.
These little gestures should not be made a big deal, do it out of the love of your heart and don't do it with the mind of expecting something similar in return...love is selfless :)
Truly yours,
