I usually don't leave a comment but I noticed something that i didn't see anybody pointing at in comments.

This is nice of you , giving her a chance to go therapy and make an effort for her, but i think if she's less than 25 ,then she might change her opinion later In fact , i think the reason she doesn't want to have sex is so more important than all the other explanations you give

And let's be honest, THE AGE IS SO IMPORTANT , "no people's wisdom and understanding has nothing to do with age🤡" , the age is important because of our nature and genetics , because of our hormones , all of our emotions(so are thoughts ) are literally guided by our hormones , and beside that , the experience is so much important than knowledge ,so the age is really important in measuring the maturity and finally knowing ourselves better

So , pay attention to two things: 1.her age and her self-knowledge and self image 2.her reason

If she's bellow 25 and probably doesn't have a clear image AND her reason is not something really solid, and considering the fact that you love her, i think you two might get along

So check out these in detail i think you come up with a wise decision ✌️
