I'm very grateful for all your comments. You have helped me a lot on turning the picture around and seeing the other side of the story. I do hope the fact that we discovered aromanticism can bring a new insight into our relationship. We respect each other enormously, have a similar perspective on a lot of things, including the upbringing of our children.
Yes, we've been together for 13 years but it hasn't been easy. I always felt incomplete and not loved as a woman/wife/partner. It's hard to find out what's going on when your partner thinks we have the perfect relationship and doesn't engage on any self-assessment or investigation on what could be wrong. I fell into a depression, was on therapy for about a year, we did couple therapy, I put my career on second place because I wanted to save our family. He now acknowledges that he faked romantic situations but in his heart he believes the whole world does it (some better than others). I now have the feeling that my partner loves me like you would love an old college good friend. He's aware of the impact of knowing about aromanticism has had on me (I finally have found the key!) and he's reacting in a romantic way which I find weird. He's texting me more often, sends hearts, kisses me more that he would before. But he's not really interested in diving into the topic although he recognizes himself in the term.
I realize this might not be the group to post my comments. Sorry for that. If any more experienced community member has a suggestion for another discussion, I'm very appreciated.
