I just don't understand this, so I want to know if any other people here have had similar experiences. I'm talking both romantic relationships and friendships. Things will be going great - you guys have been talking a lot and/or for a long time, and suddenly the other person withdraws and they ignore your messages. You never hear from them again, even though you've tried reaching out to them multiple times (in a non-clingy/non-threatening way, of course). Things were going good, and you know for a fact that you didn't say anything to upset them. You know that your breath didn't stink, or you didn't have any BO to scare them off. You gave them space when they needed it, and you talked when you wanted to. The topics of conversation were always humorous, with an occasional rant/talking from your heart type of stuff, but nothing bad/frequent enough to scare them off. But yet they just leave you in the dust.
I have had this happen in almost every friendship I've ever had, as well as any semi-romantic relationship as well. It just doesn't make any sense. I'm trying to find any of my character flaws that could be scaring people off, but I'm just not seeing it?
Do you have this happen to you, and what do you do to find lifelong friends/partners who will stick with you till death? I'm obviously not looking in the right places it seems.
I am sorry that you had to go through such difficult situations. It is not easy to make a friend because it takes a lot of effort (both time and emotions). After all that struggle, it is not nice to lose him/her all of a sudden without a reason. I understand that it is more complicated because of your personality (INTJ). I have some words of advice for you from my experience.
Before I give you some advice, I agree with what MissCris said. Blaming the reason for your friends leaving on the fact that you are a Christian is not reasonable. I quote her response because she has clearly explained why you cannot assume that.
Here's the thing- let's say that IS the reason all of these people are abandoning ship and disappearing out of the OP's life, simply because he's a Christian. Does that verse include fellow Christians? If it does, then hurray, you've made your point. If it doesn't, then the OP, as a Christian, should probably be trying to figure out why he hasn't got any Christian friends.
Personally, I am a Christian myself. But I have managed to make good friends and to keep some of them with me for many years. Some of my friends are not Christians but they have no reservations about being friends with one.
Here are some reasons why you could be losing friends -
1. Are you reluctant to get personal with your friends? Friendships won't last long if only one person is doing all the sharing. Always remember that it takes two hands to clap. How much did your close 'former' friends know about you? I am not asking you to be an 'open book' to everybody. But there must be one person who should know enough about you to guide you and support you. And that must be on an equal level - you must know as much about him/her as he/she knows about you.
2. Have your friends been the genuine sort of people who found you interesting? Or were they people who wanted some benefits and then left after that? For example, a meritorious student will always have some friends who exploit him for his intelligence.
3. How was the wavelength between you and each friend you lost? Did it match or were there glaring red flags which you ignored? A lot of 'unspoken' friction can be caused between opposing wavelengths. For example, if you are an introvert who likes to spend his time only with books and your friend is an extrovert who finds books boring but loves to go outdoors, meet people and party a lot.
4. Some Christians tend to push their friends to convert. It is a good idea to share the gospel with your friends. But there is a thin line between feeding a person some food and cramming the food into his mouth. Nobody likes to hasted into an action, especially if it concerns their morals/philosophy. If you tend to be pushy, then you have to choose between 'toning down' your evangelism or continuing the same (in which case you may continue to lose friends).
