My ex taurus as of this week ..hasnt done her share since i been with her why do i love her so much?

I was just r boring dont do anything for this relationship but i love her to death we have a connection i guess ecently with a taurus women. And for any taurus that read this ... please do not take it personal... I just want to vent and figure this out ..... she was lazy , never initiated , or went out of her way to please me ually. ..maybe once every 6 months. I always paid for everything. When we first got together she was a good girlfriend. Then slowly she started drifting off into her own life and put me on the back burner. She said she loved me. But I always had issues trusting her. She allways seemed like she was up to something. I would take her on shopping sprees and by her clothes. That she would wear out with everyone but me. She didn't cook, or clean. Never really spent money on me and if she did it was nothing special. She completely seperated her life with me from. The rest of the world ( mostly bc she was in the closet) . I chased that girl around for 2 years. Even after she stopped doing her part in the relationship. And then. She broke up with me!!! I saw her towards the end maybe once a week. I would take her out for the night. We would get intimate and then she woulf give me all sorts of attention the next day. ..and then bail. Then she was sooo busy. I'm a pisces by the way ... I'm not going to lie. I loved taking care of her. It makes me feel good to take care of someone. But she made me feel. Used. now she's saying we need. Time apart to start from the beginning again because things aren't the same when we first met... I think she's a lier and she's out there having her cake and eating it too..... what's the deal with that? She said she thinks this is "positive". Uhmm hmm .... oh and on top of all that. She thinks she's straight now.... she's out making all sorts of new friends. .. and she wants to take a break so I don't flip out if I see her out with other people??? I don't know why I love her .... but I'm always trying to show her how loyal I am .... is this normal behavior??
