Yeah, this would be a dealbreaker for me. No way am I going to risk a malicious and resentful teenager torpedoing my entire life "as a joke". No f*****g way. There are plenty of other fish in the sea, who don't have nasty teenagers hellbent on f*****g up my life. I would also give the fiancee and all of her family, including ex-husband, a wide berth from now on.

Run, my guy. RUN! This is a glimpse of the rest of your life. Wake the F up! You can find love somewhere else and with someone who won't have a psycho daughter who's out for your head. Daughter has only begun; she'll push it further because of the rush of control she had over you and everyone, what it put you through, how little trouble she got into, and the attention she received. Riley will always be there and so will mom. Riley has made it clear in a very manipulative, boundary pushing way that she doesn't want you in their lives and she'll continue. Your fiancé has shown you in an extremely transparent way where she will land when push comes to shove. You are last: kids, ex, herself, and you, in that order. Riley will always "win" even if the next thing she does against you is illegal. Even if she were to do something to you that would land her in jail, mom would simply divorce you because there's no way she'd have the person who had her daughter imprisoned sharing a bed with her.

I would also leave. But let's not forget how fụcking selfish this girl is. She's about to potentially destroy her mother's private life and happiness if the guy leaves. And for what? Because she only sees her parents as her parents. Her mother can't be happy with another man. No, she'sher mother and that's all she can be, they can't have other needs, period. So she can't have a new partner because this teen already has a father. What a selfish brat.

The daughter made a false accusation against the stepfather, implying to her school that her stepfather was a child predator and potential rapist. I feel this aspect is not being taken seriously enough.

OP may be in love, but this relationship is full of landmines, planted by Riley and authorized by her mother. This latest incident could have resulted in jail and a ruined reputation. Riley may be a teenager, but she knew exactly what she was doing in acting as if she didn't know who OP was. It wasn't a "joke," it was a stunt full of malicious intent. Her mother brushing it off is only enabling her to continue, and she can up her game. OP would be wise to call off the engagement and walk away from this spiderweb while he is still intact. It will destroy him if he stays.

Run mate run... next time, she might just actually get you arrested

I wouldn’t want to be in the OP’s place. I wouldn’t even want to be the chiropractor the OP was talking her to.

This is another of those posts that screams for OP to get away, far away from both of them. There is no happiness in the future for a relationship like this.

You need to reevaluate this whole relationship, her garbage behavior really affected you, but the mom said you have no say in punishment, hell no. That brat is just trouble, she knew exactly what she was doing, now ask yourself, is this relationship really worth the hassle? 100% dealbreaker, there is no way I would continue this, hell no!! Also, how convenient the mom forgot to call the school, hang up one call and make another, this BS about getting distracted, nope. Either of them can be trusted.

Run! You don't want to be near this toxic environment. The legal system is SO biased against men.

Fück that little brat and fück the mother for the overwhelming underreaction. My dude, you just got a severe spoiler alert for what the rest of your life is going to be like should you stay. You should make like a flock of seagulls and run so far away, change your name, move out of the country, meet some nice, one-armed, lavender picker in the south of France and live forever in bliss with them and a goldfish named Jean-Luc. Cause if you don't... well lemme put it like this: ever seen an old black and white film titled The Bad Seed?

As the future step father he should already have been involved. Given he wasnt even on the safe collection list after this amount of time he wasn't exactly trying to be involved. Step parenting takes Work. Simple as that. He is the adult. She is the child. Child. He needs to be more involved and trying, Regardless. Her actions here were stupid but she's a child. She needs to have the consequences of those actions clearly explained and apologise for it too, to the step father and to those at the school she lied to. He needs to understand that she is a Child who is struggling with a very difficult situation in having a step father figure about. Basically it's a strange man, unrelated to you, living in your home so you don't feel as comfortable as you would with blood relatives, as a female you can't just nip outside your bedroom door in your undies for a pee or nude as you Should be able to.... She'll have teenage hormones and periods to contend with but a stranger living in her home...

Tell Riley you won't be a parent but you would like to be her friend.

If OP was black... it was not a joke. It was attempted murder.
