How to build the parameters of the relationship?

I was unhappy with our sexual relationship for a few reasons:
1. It started at the beginning of the relationship, making it difficult for me to distinguish between lust and love,
2. I worried the sexual intensity of the relationship risked hurting both of us if we turned out to be incompatible, and
3. As a sex addict, I want to learn to control myself and trust myself first, to develop my own character first.

For some background, she does basically know of my sexual compulsivity or sex addiction.

I sent her the following text (name sensored):

Hi ****,
I want a sexless friendship (no sex, no kissing, no passionate hugging, no easy familiarity) for at least one year before marriage so that I can better distinguish between lust and love, and become better acquainted with her character and mine. Lust prevents me from doing that; love allows me to do so. A friendship based on lust will not last a year without sex; one based on love and a solid character can easily outlast a year without it. A friendship based on lust can lead only to a marriage based on lust; one based on love and a solid character can lead to a marriage based on the same. A marriage based on lust alone cannot survive once my wife is old and wrinkled or unwilling or unable to have sex anymore; one based on love and a solid character can thrive even then.

Will you help me to develop a sexless but loving friendship until 21 March 2016? I will not marry anyone until then. I believe a solid character is the key to a happy marriage.

At first she thought I had found someone else. She agreed but I could tell she was hurt.

I reassured her that that was not the case, that I don't mind short hugs and holding hands, even in public, that she could still hold the keys to my chastity cage. It was just that I want to acquaint myself with our characters first, and as a sex addict, it is more difficult for me to do that within the context of a sexually passionate relationship which makes me act more compulsively within the relationship and clouds my ability to think objectively about the relationship.
She agreed and seemed happy about it. To my mind, I would rather risk losing an opportunity for marriage nie than gain an opportunity for divorce later.

I have found that since we have both agreed to these new parameters that I have more control over the relationship and I think so does she. I think we both feel more comfortable discussing marriage and other subjects at a deeper level knowing that sex, engagement, and marriage will be out of bounds for at least a year anyway. I find that it feels more liberating, and I think so does she.
But I was wondering especially from the women here, if you think I did the right thing and why, and if you can see other possible problems that can come out of establishing such parameters?

I should clarify that my sex addiction had started only after my divorce and that I have not slept with anyone else since meeting my new partner. She knew of my addiction from the beginning. In fact I had confided in her and asked for her help as an accountability partner before we became more attached.

Thanks for any advice you can give on any challenges you can see in establishing such parametets.
