Lots of discussions on this here all the time. This recent thread, for example. My general view on the topic is what I said there. http://www.soberrecovery.com/forums/...-recovery.html
I broke off a long-term relationship in early sobriety. And then started a new one at around 9 months sober, and just broke that off as well a week ago. I'm beginning to seriously wonder why I did/do these things, and I'm nowhere near done with the analysis yet, just truly starting in fact.
Maybe if you don't want to end the relationship, slow down a little. Discuss all this with your partner, and try to set reasonable boundaries together that might protect both of you from too much turmoil. You could get back into it more intensely at a later time when you feel more secure in your sobriety?
