I just want to say, the fact that you recognize this about yourself and want to improve is really awesome! I read a great book about learning how our partners (and other important people in our lives) need to receive love from us to feel appreciated and cared about. It is called the 5 Love Languages by Dr. Gary Chapman.
I'll summarize to give you an idea of what the 5 love languages are:
1) Words of affirmation - verbal communication expressing love & appreciation
2) Physical touch - sexual and non-sexual to show love
3) Quality time - focused time spent together without distractions
4) Acts of service - anything that can ease the burden of responsibility or show that you listen and care
5) Receiving gifts - physical symbols that show love and effort
Maybe this is a great opportunity to have a conversation with your wife and find out how what makes her feel more loved. If nothing else, it is a great place to start. You could even get the book and read it together for some bonus points 😍
Don't stop trying, I love that you love her so much! All the best to you!
