Some people think its hard to go back but its not,just repent and truly belive you did something Vullger and wroung that is all.
I mean my dad Had you know what with anouther gal while he was married so he got Excummunicated,he knew it was wroung,and he was also a returned Missionary.He has married the gal and has also broken the law of Chasity.He tells us to be close in the church so we won't make the same mistakes.He I bet had a problem about going back to church but as times progressed he finally came back for like Sacrement,its cool.Anyways,their are worse sins,that sin however can be forgiven.Soooooo forgive and go back its as easy as that a'ight?
