This is a passionate topic for me as it holds personal history. One of my "ah ha" moments in my first experience with delving into this relational world was, I'm REALLY good at stuffing things. I thought (incorrectly) that this was a sign of strength, flexibility and just being a good wife. Everyone's reason for not asking for what they need or expressing discontent due to an event may be different but the results are the same. Here are some examples...
1) Avoiding argument
2) Afraid of not being heard
3) What's the use, he won't change
Sometimes we're able to say that we're uphappy however lack the follow through when/if it comes up again. In other words, we boil slowly, thinking thoughts of "it's not worth talking about again", "this is pointless, what good is it going to do". What is the problem here? We become resentful. In the moment, it's not so bad however over time the resentment grows into resignation. Have you ever really thought about resignation? Simply put, you just don't care enough anymore. You've given up. This is the kiss of death to our relationships. When you stop caring, you stop loving, cherishing and hoping. Resignation is an explosive with a very long fuse. The trouble is, the fuse continues to shorten until it's too late. KABOOM!!
Did we perhaps say at times that we were unhappy? Most likely. Should our partners have gotten "it" before it exploded? Yes. Could we have done more to empower the shift? Probably.
If it's important to you, hold your feet to the fire and ask for what you want. It's not easy, this I know. Ask yourself before you sweep it under the carpet. Do I have any resentment about letting this go? If the answer is yes, go back to the table and ask for what you want.
Challenge: Make a mental note of the the things you let go of. Are you doing it with grace or with resentment? Is there something you can follow through with your partner about? If there is, take a breath and talk about it.
