No one here can tell you if you would be excommunicated. Is it possible ..... Reading over what you said .... Yes it's possible. That's why you need to tell your Bishop what you shared with us. As a Mel Priesthood holder and Temple rec holder you did make some covenants. Hope all goes well for you. Being a Mel Priesthood holder your Bishop will then speak with your Stake President and he will decide whomwhatnwhere and when. The Stake president is a council is held will tell the Bishop if he will take care of it or he will tell the Bishop to handle it.
