20f 21m is this emotional cheating or what

Do you think this is emotional cheating?
I specifically don’t want my boyfriend talking to the girls who come to his house and he constantly tells me he doesn’t, he would not like me speaking to other guys at all and I do not and he told me he hasn’t been speaking to girls at all at his house for nearly our whole relationship because he has a lot of girls coming over because he has a sister of similar age and theyve become more like family friends.
Well 1 of these girls called him hot and the other was snapping him and showing interest in him a little before we started dating and I especially specifically don’t want him speaking to those girls and I found out he’s been lying the entire time hes about speaking to these girls when I found out through a video someone else took that he was in fact talking to those 2 girls plus more girls in the house and has been talking to girls in his house our entire relationship.
He also told them he doesn’t have a gf and excuses this by claiming he told them hes “seeing someone” months ago.
He also claims he could not not talk to those girls bc he knew them his whole life now changed it to he barely spoke to them and it was a 1 time thing .

TL;DR: My boyfriend told me he hasn’t been speaking to girls at his house for almost our whole relationship, but I found out through a video that he has been the entire time—including with girls I specifically didn’t want him talking to (one called him hot, another was snapping him before we dated). He even told them he doesn’t have a girlfriend, then excused it by saying he told them he was “seeing someone” months ago. Now he keeps changing his story, claiming he either had to talk to them because he’s known them his whole life, or that it was just once and barely anything.
