Does she just not love me as much as I love her?
I hate to be the one to burst your bubble, but you asked the question.
Answer #1 - No, she doesn't love you the way you love her.
Answer #2 - No, YOU don't love her the way you think you do.
You thought hooking up with a party-girl-mother, getting engaged in 3 months and moving in together would equate to an
easy relationship? And you think SHE'S got issues? Dude, you got 'em, and you got 'em bad.
You are dating a real person, with real habits, real baggage and a real personality that is not manipulated simply by you being her sugar daddy and treating her like a queen (or your idea of what that means.) She's still herself.
And you are still you. Sit still for this and listen:
You don't love her like you think you do, not at all. It sounds like you love the idea of what she SHOULD be and isn't, you love the idea of being the provider and being admired and she isn't responding that way. You love the family image of what your fiancé should think of you... and she doesn't.
Dating is supposed to be investigative. You date, find out why you shouldn't be together and move on. That's the formula. After doing that successfully for years, you finally find yourself in a relationship where no matter how hard you look, you CAN'T find reasons you shouldn't be together... so you stay together. A year to two in you get engaged, married, THEN move in together.
You, on the other hand, are treating this WHOLE scenario like she and the universe owes you some respect simply because you're so nice. What's that all about?
Go back to the basics, man. Date for the enjoyment. Pay attention to who people ARE, stop pursuing who you
wish they were, or who you are trying to make them. Never going to work that way.
This girl leaving is a chance for you to undo the damage you've done to your life and are attempting to do to her life. She doesn't need to change anything for you, she really does get to lead her life the way that makes sense to her without you giving her grief about it. Really.
If you two aren't compatible, then you aren't. It's a SUCCESS that you discover that and move on without destroying each other in the process. It's a reflection of how mature and wise you are if you can do that. Can you?
Keep in mind just how out of control your whole story turned out. She didn't do this to you. You did it to you.
And remember, I'm on your side. I want for you all the things you want for you, all the things your story make it so clear are in your sights... I want that for you, too. I'm telling you straight you won't ever get it the way you tried here.
