Honestly? I would stay far away from him. Sometimes you have to be a “jerk”. He’s shown you what his real intentions were the first couple of times. When people show you who they are, believe them. I just have “danger will robinson” stuck in my head.
Sorry, this is kind of cute and funny but also awful. I think you’re going to have to send him a text being firm and forward with him. Do you want to be his friend at all? If not, send him something like, “I don’t want to be friends with you. Please stop contacting me.” and then leave it at that. If he still contacts you, contact the head of whatever Christian organization he’s working with or even contact the school and see what they say.
@iamjack let me break this down to you as an adult to a college kid: STOP communicating with him.
He DOES NOT WANT TO BE YOUR FRIEND.
He, as many over the top evangelical Christians on college campuses are, TRYING TO PREVENT YOU FROM BURNING IN HELL.
Yes, I have been told that some of these folks are so ever longingly convinced they must save you from the flaming fiery pits that they will practically latch onto you for dear life.
He’s found himself a non Christian and his passion, unswervingly, will be to NEVER let up until you make it very clear you NO LONGER WANT TO CONTACT HIM.
When you see him, go the other direction. Don’t text him. For the love of God (any God, or none at all) stop buying him presents and feeling guilty.
It’s called HARASSMENT and you are playing the willing victim. Get away.
I think being really honest with him is the best course of action. I’m a Christian, and while I’ve never done something like this, it wouldn’t offend me if someone was like, “Dude, seriously, I’m not interested in going to church, and I feel like you’re giving me gifts so that I’ll go. Please stop.” If you think he actually wants to be friends with you, you can try it out, but know that in the back of his mind he’s probably thinking, “If we are friends for a while he might eventually come to church with me and then become a Christian.” So yeah, I can pretty much promise that he is hoping you’ll become a Christian, so if you’re not comfortable with that, end the relationship. There are a lot of Christians that aren’t pushy about making friends just to convert them, but it doesn’t sound like this guy is one of him. Good motives (at least in his eyes - I know not everyone would agree) but really overbearing and somewhat rude methods.
Oh, and definitely tell him very strongly that you don’t want him sending cards you your house. (And don’t give him your address.) I mean, he should respect your wishes no matter what, but explaining to him that your parents would be upset with you might make him less likely to send a card. If he sends it anyway, he’s definitely a real jerk. Anyway, best of luck!
