I'm a man recently married to my female partner of 7(ish) years. I definitely suffer from depression-anxiety, I have always been a very pessimistic person, and I never seem that excited about anything.

This is only one detail in the series of shortcomings and problems I've been having in my relationship.

Although I think she's the most incredible person inside and out and would have a hard time finding any criticisms for her, I basically never compliment her. She tolerated this through most of our relationship. Recently, alongside other issues, she's told me that she really needs me to compliment her and convince her that I actually care about her.

This is a very reasonable and simple request, but I have hardly changed my behavior even though I honestly want her to be happy and feel good about herself. It's almost as if I'm being stubborned and resistant now that I'm being asked to do something. In the moments that I should be expressing my feelings and wanting to be affectionate, I generally freeze up and avoid, or maybe eek out the same few nice things that I always come up with.

This is the way I've been through all of my relationships and only in the first few months do I feel genuine excitement and express some of it (usually still not in the form of compliments).

Am I just an *******? Unfit for a relationship? Sociopath?
