Search Results: guys will disappear

I have been really close friends with this guy for a long time ( 10 years). If we have been busy, we both tend to draw back to each other after not talking for a while automatically. Since couple of years though, our conversation seems to become upsetting and we argue and stop talking to each other. Recently, we have resumed talking again. The convo is more long distant since he moved abroad for work. He first mentionned that he is just trying to change field and got the opportunity in another country. Mentionned he will be back in few months. I was saddened a bit and stated it to him. He assured me that it was just for 6months. He actually persuaded me to keep talking to him because he misses me. Later, he actually started to withdaw from messenging. So I didn't wrote him back. He then got upset that I stopped writting and I explained that there was no point if he wouldn't answer. Now that the days are coming closer to his arrival date, he said that he might not come back. He plans to find a girlfriend get married and stabilize which he wasn't able to do Here. I told him I had a feeling he would say this. He got upset when I later said he is stringing me along even though he has other plans. He then accused me of wanting to stop talking to him now. I told him to stop whinning and if he wants to talk he can still write to me. Couple of days later he sends me a message and a video. I was busy so I check it out the next day wrote him back we laughed. I then wrote him some more that day but no reply from him. I assumed he must have fallen asleep. I noticed he never replied after 2 days and wonder what was up. wrote to him jokingly " So you disappeared?" and made a crying face emoji (all jokingly). No answer. By the next day, I noticed he blocked me.

I wasn't that surprised with his passive-aggressive behaviour but it still got to me. Personnally, I'm done with him for life.
Did any of you went through something similar... how did you handle the aftermath of it?

So, I turn 18 in two weeks and I barely have any friends. It's been like this for seven- eight years. Kids in my age group cut me off after a few months, people online stop talking to me after a few months, I feel like I'm easily forgotten by people and people are quick to ditch me. Even when I make friends I typically think of the date or deadline they will stop talking to me and cut me out their life. For example I made a friend in my neighborhood who was supposed to go to my school, he told me we'd be friends but I thought that once he started making friends at our high school he'd probably ditch me and end our friendship to be with other people there. :/ we had a great time together and I always wondered if my feelings were normal or just depressing. I don't expect people to even like me anymore. Sometimes kids I was friends or talked with would disappear from school and never show up again. I can't see myself making new friends, having a boyfriend, having a normal life. I imagined myself getting pregnant then thinking of the guy abandoning me and me being a single mother. In 20 years I see myself being completely alone with no friends, little to no family, I'll be living alone and living my life as a loner with a boring, mediocre career that only pays enough for me live in a small one bedroom apartment with barely any social interaction with people being at home all day Watching YouTube videos I don't even see myself traveling or dating. I don't even see myself really happy... Is this normal? I see myself dying old, alone and thinking that it'll be a week or two before anyone notices that I'm gone. Is this normal or I'm I depressed?
