Look, you love her, so you are going to see things through a specific lense that is most likely to give you hope.

Waiting patiently for her? She JUST GOT engaged. She JUST chose him over you. That is a pretty dang clear signla that she is more commited to him than she wants to be with you. Because again - there is NOTHING holding her to him. She could have said no. She said yes.

No relationship is perfect, so the issues she is having? Sure, they're real and legit. But she continues to CHOOSE HIM and not you. You are being used because you give her the undivided attention, devotion, and emotional gratification that she wants. She's cheating on him, with you, for that purpose. Like almost all cheaters - she loves the person she is in a relationship with, and wants to stay with them.

This relationship she's been in with him, you said has been going on for what, a year? She's known him for 14 months, and been "in love" with you for a year? So... two months after she MET him, she realized she loves you. Yet she didn't end her relationship with him. She continued it, for a whole year... and is now engaged.

I really don't understand how you can't see that. The entire time, she has chosen him over you. Every day. Every single day she chooses him over you.

You're separated from your past wife. Why aren't you free to date and live how you want?

You're making soooo many excuses for her. If she's cheating on him with you.... even if she DID break up with him... she'll just do the same to you the moment she feels she wants something you aren't offering her. That's usually how it goes.
