I am just gonna say this in the briefest way possible for me Steven : Get out of this ASAP

This does not look good from any angle. Yes, all those feelings of love that were(or are) there due to all the moments that happened (in the past) between you too makes it extremely difficult, but just leave this thing. It will be hard (as you already are experiencing) but trust me, once you start taking steps, slowly you’ll realize it was the better choice. Moving on is the hardest part and it is scary but there is one more thing which even more painful and scary and that is REGRET. Don’t waste your time on this relationship anymore, learn from it and move on. If you do decide to move on I suggest you go a for a no-contact period for some time.  However keep your emotions aside when deciding and be a bit more objective and see what kind of behaviors she is displaying instead of what she is saying. Actions tell everything. Don’t go by words alone…just don’t.
