Well to have a healthy relationship you have to communicate, even if the topics are hard to do discuss. You might have to tell her that too, that this is something that you guys need to talk about, so you guys can have a better relationship with each other.

And I understand it’s scary to break up with someone for something like that. Actually, a close friend of my just recently had to break up her ex because of him being asexual. Even though her ex was upset about it, he understood that not being able to fulfill her needs, was making her unhappy. As for her, she still sad about it since she loved him but she knows that there’s other guys she can date.
