Wife found out

I have been married to a wonderful woman for 12 years now, i have talked to her in the past about trying a threesome with a guy, and told he i thought i was bi, she wanted nothing to do with it,

About a month ago she found out i was sucking a friend off somewhat regularly, i really enjoy giving guys head. not really attracted to guys, just love sucking cock. i love my wife.

Here is the dellema. I don't think i am willing to quit sucking cock. i would rather her leave me and through i all away than give it up.

What do you think, anyone been through this situation? any advice would be helpful.

Thank you
