The selfishness of the "outed" spouses on this forum still amazes me, unfortunately I have to agree with the other posters , WHY did she come out now, OF COURSE she wants to remain best friends and have her dates as well ( its called cake- read CHUMPLADY.COM) she wants her life to get better and to hell with yours,
You are still very early days and the shock and grief is overwhelming I know, but she is not committing to your marriage she wants to experiment , therefore you need to lay it on the line,- say NO , no friendly outings- see how she reacts then, that will guide you
Blessings
