I read a good article somewhere about the importance of spouses showing each other appreciation. For a relationship to be strong, a couple needs to keep giving and know what to give. That includes showing appreciation to each other, which is also a form of giving.
In general, if there is something that one spouse needs or something is bothering them, a couple should discuss it with each other, and then work something out and implement it. I sometimes have a difficult time with expressing myself to others. But I find that it is reaslly for the best that I tell them nicely what’s on my mind, instead of holding it and later exploding, lol 🙂
