Is he on games?

Okay so early in this “relationship” there was a girl that suddenly added me on Snapchat. Something told me to

add her back so I did she texts me fast af talking about “your man is messing with me” “he’s doing this, he’s doing that” all of that stuff so I confront him about it and he’s like “I have no idea who she is she’s probably some crazy ass ex” so we argued a little but soon got over it. Until...last night ANOTHER girl added me on snap talking about “your man is in my phone sis I’m telling you this Bc I don’t want you looking stupid.” So I told him about it again but this time I’m realllly suspicious now so I asked for some space. Now I don’t know what to do.
