Got I sometimes hate this show.  AARRRGGHHH!  

Not because of sweet ball-punching Baylen and her sweet getting-his-balls-punched fiancé Colin.  But because of Baylen's meddling, controlling, pretending-to-be-sweet parents.  Do I think they're narcissists?  I cannot tell you that with certainty, because what we're being shown is TV and not real life.  So while some parents (like the mom Julia on "My Orthodox Life") are blatantly narcissistic, many are covert, which makes them hard to spot.  And we have no idea how much of the reality show is put on, compared to their actual life, so on the show, it could go either way with her mom and dad.  But I will say that they are definitely going to be an issue for their relationship and unless they back the fuck off, Baylen will be a young divorcee soon enough (if they even ever get married).  

Here's what needs to happen whether they are narcissists or not: 

1. Miss Baylen needs to remember this: her first priority now needs to be Colin.  Unless he's a dick to her, then fuck him, but he's not, so when you're getting married, you need to put your soon-to-be spouse first, not your parents.  Fuck what her parents want, Bay's life is about HER and her man now.  Her father not giving Colin the blessing he asked for?  Her dad owes him a huge apology, not apologize to Baylen.  Colin needs to hear it straight from the horse's ass mouth.  Because saying that shit was a VERY horse's ass thing to say to him.  Their only response should have been "Of course we give you our blessing!  You're a great person!  We love you like family!"  That's it.  Anything else is a controlling manipulation. 
2. Miss Baylen needs to remember also this: her parents are NOT perfect and they do NOT always have her best interest at heart.  They have what they think is her best interest, but they do not see her.  Not as she is.  They see her as she once was.  And they are stuck in that moment.  And she needs to push them away if she has to in order to release the amount of control they are trying to exert on her (about her wedding, etc.).  She needs to get some counseling to open her eyes to the fact that her dad is very POSSESSIVE of her, not just "protective" as they all say about him.  The family has been conditioned to see this as "protection", but in reality, even if the dad doesn't realize it himself, it is clear as day possessiveness.  (I always find this gross...parents being possessive over their children....it's like dude, you don't' own your kids and what are you even trying to possess??)
3. Baylen's parents need therapy of their own to learn to let the fuck go.  Because GEEZUS.  It actually angers the hell out of me to watch this show because of them. 
4. Colin also needs therapy.  They ALL need it.  Together and separate.  To deal with this mess of a life that has been created by her parents possessiveness. (And if by some strange weirdness they are reading this?  Know that you are being possessive, not protective.  There is a fine line between the two and the minute you start meddling into your child's life and not allowing her to grow and change and make her own choices in life, that's when you know it's possessiveness.  Protectiveness is guiding, possessiveness is controlling).    
5. Colin needs to stand up for himself.  Not just to Baylen (not that she's doing anything wrong other than letting her parents overstep hers and her boyfriend's boundaries--though that's bad enough), but to her parents as well.  He shouldn't be a jerk about it, but he needs to set FIRM boundaries with them himself, and not allow her father to steamroll him at every turn.  Again, a good reason to go to therapy to learn how to do this.  
6. Baylen needs to set boundaries for her parents as well.  Colin's birthday should NOT be the time or place where her parents bring up something as silly as religious counseling.  I have a son who has some severe issues and I am terrified of sending him out into the world too.  But I tell you what: if my son had a significant other who made him better and loved him even knowing his issues and treated him well?  If that person asked for my son's hand in marriage?  I would be jumping up and down screaming in joy for them.  Because THAT is how you support your child.  Not whatever the fuck Baylen's parents did and continue to do.  They are actually quite horrible.  Even more so because they make Baylen believe they are only doing this for her and not them.  No, they are being quite selfish in how they're approaching their daughter's independence.  Yes, I get it, but also, doesn't matter.  My husband's parents did the SAME shit to me and my husband, and guess what?  We're 20 years into our marriage and we don't speak to them anymore.  Is that what they want??  Because that's what they're going to end up getting and rightly so.  So before that happens, BAYLEN needs to set those STRONG boundaries with her parents and not allow them to interfere with her marriage.
