Always wanted a Working Partner & Helper.

I find it hurtful how 10 loving years are overlooked and put aside and 10 uncaring years are taken into total consideration when taking actions or decisions. 
Though in live in Relationship, i consider my partner my wife.
Under the existing Portuguese Law in Goa, due to common habitation as man and woman, if one of us tends to seek recourse in the law of the land, then we are considered to be husband and wife under common law marriage, due to the live in relationship of 20 long years. Nowadays love or arranged marriages, exchanging marriage vows in temple or church or mosque, or the marriage registrar's office, the tremors or marriage quakes can be seen in all relationships within 7 years. So we have lasted fairly long enough. 
Always wanted a working partner.....Here is where the trouble began after 10 loving years.
Right from day one, my partner has been a helper and supporter in everything that i do for a living. I liked that. I loved it. I believe that in case i depart through death, the other partner should always be able to stand on her feet and able to maintain the same standard of living. I like and love woman who are working, financially independent or who are able to contribute to the finances of the family.
The last 10 years with me entering into a new field of business in computers, i found my partner to be lagging behind in support and in the active work issues. Slowly she started disconnecting herself from work issues. In her words she wanted suddenly the life of a Queen. But i was not and never been a King! I found this sudden distaste for any kind of work disturbing. Thats when my statements and comments towards her started becoming rude and crude. Sad to say, since she was not actively and genuinely participating in my office work (all the time wasting time fooling and flirting on Facebook), made me more abusive towards her in words and my reactions and outbursts. This took a serious toll on our relationship.
Since i had become terribly unappreciative and negative and all the time nagging and cursing about her not doing anything in her life and wasting her precious time. This led her to doing some serious misdemeanor. This made things even more worse. 
Currently we have mutually initiated separation, giving each other time to ponder if this relationship has to continue. I am promising to one and all and to myself too that i will improve on my verbal behavior with my partner. I want her back. I need her. She is my total moral support. But when she is in front of me, there is Like / Dislike confrontation within me. Some things i like, somethings i don't like about her. Some things i Love, somethings i hate about her. 
Will i be able to treat her the same way, as i was treating her humanely, womanly and lovingly, even if she continues to refuse to do any office work? 
I surely need some help here.
