My profession is a dating coach. I'm only saying that so you understand where this advice comes from.

You are in a very unhealthy relationship. You need to stop fixing her problems for her and providing for her. She needs to take personal responsibility. There is a possibility that it could end your relationship. It's important to realize that there are plenty of girls out there.

People get comfortable and invested in relationships. All of the shared memories and effort you've put in so far makes it difficult for you to think of life without her. It's not as hard as you may think to find another girl that is better than her. Then, set better rules in the next relationship.

I've seen too many guys who were in loveless relationships too long come to me, saying they wish they had ended things sooner.

Just my 2 cents.
