Is she cheating?

So we have been together for 8 month. Lately I keep finding good morning videos with kisses and stuff that she takes on her phone and she doesn't send them to me. She says she just likes taking videos.. Is this normal girls behavior or are these videos for someone else?

Also on one of the "private pics" she sent me before there was some text that she covered up with some random words and she said it was text for me but she didn't like it so she changed it by putting the new text over it.

Also she keeps creating new accounts on Facebook and snap and stuff.

P. S : on the second month of our relationship I caught her flirting with another guy and we had a big fight in which I wanted to break up and she kept swearing she loved me and would never talk to another guy again and shit.
