In my opinion, if one omits the masculine divinity to focus solely on the feminine then what you are doing is no longer Wicca. There's nothing wrong with that, and there are many people who do just that, but a different name other than Wicca would describe their path. Perhaps Witch, perhaps Goddess-worshiper would fit what you do better. But Wiccan core beliefs do involve both God and Goddess.
As Nekoshema pointed out, Wiccans honor the Goddess of the Moon and the Horned Lord. But our Patrons are something else again. Patrons are Gods and Goddesses who have chosen to have a special relationship with us and we with them. A Patron can be any Deity from any pantheon.
Sometimes we mistake a Tutelary Deity with a Patron. Tutelary Gods and Goddesses come into our lives to help us master a particular lesson we need to learn. Once we have done so they may remove themselves from close contact with us although they always have a special place in our hearts. Perhaps what you have been experiencing is a Tutelary Deity and the reason you now sense a distance from them is that the lesson they needed to teach you has been mastered.
There is an excellent book on working with Patron deities called " Devoted To You " by Judy Harrow that you might want to read whether you choose to continue to identify as Wiccan or not. I highly recommend it.
