Love languages. Find out what Hers are. Maybe the way you give love or perceive it isn’t the way she interprets it. Doesn’t mean you don’t love her, but that could be. For example, mine are physical touch, quality time and words of affirmation. My wife’s are acts of service and quality time and physical touch. I always thought saying words of affirmation and giving gifts was the best way to show love. Although my wife appreciates it, her go to is acts of service. Taking the trash out, doing dishes, yard work, cleaning up. Stuff like that. Where as I see those things as just necessary responsibilities and took me a while to understand. But that’s my two cents. Hope it helps. My only guess based off of what you said is she may have already expressed it to you and felt unheard as actions may have not shown otherwise even though you whole heartedly love her. I went through a similar phase and this is what helped me get out of the rut.
