I'm scared he might be cheating on me.

I already posted a thread about my relationship. Here is a sum-up to recap :

Im in a distance relationship since last month, we met in March, etc. We had a big huge fight last week on wednesday and since, I got no news at all even if I tried twice to text him. Nothing...

Now, I checked his accounts and I saw that he followed someone and gained a follower on a certain social media, idk who tho, and on *** I see his score increasing a lot today when he is like : "I'm not that active"... Last time he got +100 scores on a week, it was because he had to send pictures of his studies to classmates, but right now we just came back from holidays yesterday... And I'm scared that he won't come back, forgot about me, met someone else and so that could be why he added someone on a social media and on snap, his score increases a lot (it increases by sending or receiving pictures btw)...

I dont know what to think .-.
