My flirt (M19) blocked me (F19) for no reason at all...any advice?

Hi guys. This is my first time ever posting on reddit ! Okay so actually I have a problem and I would like to know your opinion on this.

It has been almost 2 month that I’ve been flirting with a boy (we are both 19yo). We clearly liked each other but we wanted to wait to see each other before making the relationship official (it was a long distance relationship so we obviously wanted to know if the bond was as good than by messages).

Like I said, for 2 month, we were having fun together, calling, talking and flirting, everything was alright. BUT I woke up this morning and find out that I was blocked on EVERY social media we were following each other.

The thing is, there was no apparent reason to block me, we never ever had arguments and (I thought) we had a good relationship. Also, 2 days ago, he was not feeling well and for the first time he confessed to me about his problems (that he never really told about me before). It is a thing that he never did (he told me that). I said that I was ready to support him and love him with all my heart, and really wanted to be with him. He said that he loved me too and wanted us to be official (I said me too but that I wanted to see him in real life before, thing he agreed on)

Now, I’m blocked, and he didn’t tell me why before doing it…

There could be many reasons :

• He was not ready for long distance : I don’t think so because from the beginning he said he was okay with it + the distance is not THAT bad

• He was not ready for an official relationship : same I doubt it because he told me many times he loved me and wanted to be my boyfriend (he almost acted like one)

• Be cause of his problems, he thought that he would hurt me and didn’t wanted me to feel bad about him (which is nonsense as he didn’t told me anything before blocking me so it is contradictory)

• He found another girl OR I was the other girl : it may be a possibility but I really doubt it because I (supposedly) am his first « girlfriend » and looking at the way he is living and his values, I don’t think he would ever cheat on me (there are always surprises but yeah…)

• He doesn’t appreciate me anymore OR never did : but I don’t think he’s capable of any kind of manipulation like this (but like I said, we can be surprised…)

That is my opinion on this, I wanted to know yours

I know I shouldn’t think about it that much but I am very confused...(I’m thinking about dm his bestfriend to ask but I don’t think it’s a good idea)

Thanks for help !
