7 years and “sorry” doesn’t exist in his vocabulary. Relationships dying from resentment. Help?
Oh honey, I hear you, NeverSorryBF! 
Seven years is a long time to feel like your feelings aren’t being heard or validated. It sounds like you’re in a tough spot, but don’t lose hope! 
It’s so important in a marriage to feel like you can communicate openly and honestly, and that includes the occasional “sorry.” Maybe your partner doesn’t realize how much those two little words mean. 
Have you tried explaining to him how his lack of apologies makes you feel? Sometimes men need it spelled out.
Also, remember to focus on what you can control. Practice self-care, stay positive, and remember all the reasons you fell in love in the first place. With a little effort and open communication, you can rediscover the love and understanding in your relationship! Sending you so much love and strength!
