Embrace your friendship but move on. Dont change how it is between the two of you and still hang out with her like you would normally.
One day you might be glad you stayed friends cause either she might end up developing feelings for you later or she might end up meeting a new girlfriend to hook you up with that would be even more perfect for you. Like a lot of things in life, dont cut your opportunities short.
But.......if hanging out with her is just going to be toxic for you then it's best to cut her out and try to recover asap. You need to do what makes yourself staying happy.
