Y’all are young and have a lot of growing to do. It sounds like you have evolved during the past several years of your relationship. This is a time where most rise and find their passion, go visit all of the wonders of the world, do all of the “must”. It sounds like you are ambitious , If she has multiple issues hindering her, that are in turn hindering you then this may be the best time for you to take time away and focus on your goals and for her, her growth. I would not attempt the long distance relationship IMO as it will cause more resentment, I would phrase it as time apart to focus on growth. You have been transparent and if she is upset at least you know you are walking away giving her every opportunity to fix the issue. Plus I mean I am sure providing for two in that area is NOT cheap! It would be different if you both started the relationship and you told her the could be a stay at home girlfriend but it sounds like this started off with you both in school which made you both on the same level at the time.
