For my background info, feel free to read my post history where that goes more in depth.

I'm a 22m. Recently I've been much more open and confident about sharing my faith with the broader community and as a result of this, I've had a few Christian's roughly around my age come to me for advice with understanding the Bible.

1st, a 23m. He was baptized as a baby, left church when he was growing up, went into a life of drug use and seemingly giving up on going to school or having a career , and then one day came to me for advice because his then girlfriend had broken up with him because he didnt have a relationship with Jesus and didnt take it serious. He asked me how he could know Jesus, and I gave him his first Bible and that was cool.

(He ended up screwing things up with his ex because it seemed like he only showed up in church for her. He was pretty needy honestly and despite my best efforts things went South. After that situation he didnt come to church for about 5 months, citing that it was a long drive for him (45-50 minutes which I understand).

2nd, a 17f. She works at a nonprofit that I used to volunteer at, and she mentioned a few times when I came in to visit that she had spotted me at church but had been too shy to say hello. Then the next time, she approached me in church and offered to buy me coffee, (I agreed, and then paid for both of us when we got to the front of the line) and in passing she asked me a couple of Biblical questions which I was happy to help with. She's grown up in church, super good manners, and I'm always happy to help her because she's so darn polite.

So the 23m ends up getting a job at the nonprofit where the 17f works.

He then hits me up out of the blue, telling me about this new girl he met at his work. Saying that she's a Christian, and that she's super attractive, etc. I was cordial, saying that sounds awesome, etc.

I had no idea it was her until he sent me a picture. I was a bit shocked, because she's 17 and he's 23. He's saying that while they were working together, that they hugged, and that he kissed her. (He also said she didnt kiss him back). He said she was being shy. I questioned him about it, saying she's only 17, and asking what he wanted to accomplish by pursuing her. Let me be clear, in a different time I know a 23 year old and a 17 year old is no big deal at all. He gave me vague answers about how "she's really sweet and I want to pursue her when she turns 18", etc. I was fairly annoyed about it because it seemed like he was trying to justify his lust towards her.

Then a few days later this past Friday, she texts me, saying that she would love to see me at church on Sunday so she can talk to me about something. I replied saying that I could potentially see her in passing after service before I go to my small group meeting.

She agrees and says she'll grab coffee for us. She then ended up asking if she could come and sit with me in service, which I was iffy about, but since she's like my baby sister I said it was fine.

So this is where things get weird.

I arrive at church right before service. I ended up bringing coffee for both of us again, (because I'm not going to let my baby sister pay for me). This is important because right as I walk in, I run into the 23m.

I'm really confused because he said he doesn't come to church because its 50 minutes drive and I haven't seen him in church for like 5 months. He asks me as soon as we meet "who's the coffee for"?

I was like "17f's name". He says okay sweet, let's go in. I was sort of confused because she never said that he was coming with us. But I brushed it aside as nothing.

So I text her, saying: "We're sitting front left, also this guy 23m just showed up! Come!".

She doesn't respond for 30 minutes and then says "I'm so sorry, but I think I'm going to stay in the back, can we meet afterwards"?

I'm so confused by what's happening now.

So service ends, and 23m and I split..

Then 17f finds me a few minutes later. She is fully in this weird, exasperated state. Says that she was trying to be nice to 23m, but she thinks he has a crush on her and she just doesn't want that. She said there is too big of an age difference and that he is acting very strange, messaging her a lot, and she is very creeped out.

She believes that he stalked her to church. Cited that he lives very far away and that theres a million churches in his area he could go to. She asked if I could protect her because she doesn't feel at all comfortable around him because he always tries to touch her and hug/kiss when they're alone.

I offered to her that Jesus should be the model always. That she should always strive to be righteous, and holy, but that Jesus has said nothing about not being rude to folks who cannot take no for an answer. I cited that Jesus was quite rude to the Pharisees. I told her to not lead him on and to be very clear with her intentions.

(Side note: theres always the chance that she was being a bit flirty and enjoyed the attention she got from him and encouraged it until it became too much. That's my belief based on the info I have).

I told her that I'm always here if she wants to talk, but that she should speak to her Father about this before me. I'm just here as a resource when you need it, but it's not my place to tell you what to do.

How did I handle this, and what should I do moving forward to deal with this?
