Super low libido

Ok, I have never considered my self a sexual person and honestly Idk why. My hormones level are normal I think, I really love my husband, my stress level are no too high, I have two kids, a nice house and a dog ... I can say I’m happy ... it’s just my sex drive is so low that gives me problems every month with my husband. I could live without sex an entire month without me noticing and I’m perfectly fine with it. On the other hand, my husband’s sex drive its very high and its driving me crazy. It’s hurting our marriage and sometimes I feel I cant deal with it anymore. I feel sad for him at the same time cause he had the bad luck to end up with me lol.

A bit of our story ...

We where young, I got pregnant at 19 when we where just fooling around, he said he will take care of me and our baby (even back then my sex drive was low). It was not a love story at all lol... his parents said they will help us so he could finish studying. I think we fell in love while we where trying to figure our future. I got pregnant with our second child just before he finished college, we moved to our own house and we’ve been together for 15 years so far.

He’s an amazing man and father, he’s kind and I feel honestly like I don’t deserve him. He’s not happy with all these discussions about me not want it to have sex and I’m soooo tired too. We spent some time in counseling too but I felt like it was a waste of time :/ ... could I be asexual? And if is that the case, should I let him go and let him find someone that will make him happy? Idk ... this is hurting me too.

Any thoughts?
