SO addicted to Ps4

My SO got a new ps4 a couples months ago and everyday after work he has been playing it non stop until 11pm. I go to bed alone. We barely have sex time or any time for us anymore. Last night after showering I come out and hear him on the headset and he was talking and laughing with a girl. This is the first time I hear he’s playing with a girl online. I was actually hurt by it because he is not dedicating any time for me anymore but is now laughing and talking to this girl. Am I overreacting? I am just feeling lonely and he tells me it’s just a game.
