We moved in with roomates!!!!

Me and my bf we are both 20 we moved in with some roomates and since then he doesn’t want to have sex as much or when he does it’s super quick and doesn’t feel as good as it used too. Honestly he doesn’t want to spend as much time with me either he just wants to hang out with our roomates all the time instead of me and then when he gets bored of them he comes to me touching me and kissing me after days of not touching me in anyway! What do I do it’s super annoying because we used to spend time when ever we could now when we have time he doesn’t even notice me :(
