This is just a snap diagnosis of your difficult situation based on very little information and never having met you.
You sound pretty needy (not a criticism or judgement). She sounds like she's lost respect for you for some reason (too needy maybe?) If my wife asked me to move out because she needed space, I'd say "you need space....you move out" I can't imagine thinking so little of myself that I'd tolerate being treated that way nor would I ever grovel my way back into her good graces (unless I did something wrong)
You are in mourning over this...don't make any big decisions (relationships, moves, purchases etc) until youve put some time behind you. She may think more of you if she sees you've genuinely adjusted and are thriving and doing well without her. Behave well and be an adult about this. No one likes to be clung onto and no one respects someone who they think will fall apart without them or is always at their beck and call. Know your own self worth and without being militant about it, don't allow others to walk over you or have the power to devestate you like this.
