Is this right, Getting married to your stepbrother or adopted son of your father?

I have been wondering how this two guys feel when they got into each other now they are engaged, i know for sure that if their mother were to be alive today, this might not have taken place…

The excited couple showed off their wedding rings and passionately kissed for the cameras in a parking lot outside their local CVS/Pharmacy in Georgia Shrugging off detractors who have taken issue with the fact that they were both raised as brother and sister after Nick was taken in by Bobbi Kristina’s late mother, Whitney Houston.

If you were to be in their shoes, how will you feel making love with your brother, talk more of getting engaged?
