Mental health

my boyfriend & i have been together for 2 years & hes told me before his thoughts get to

him a lot & its happened before but the past few weeks have been the worse. hes really distant he doesnt talk to me as much the more i try the more he pushes me away he says its not intentional but it feels that way when he used to get this way he would want me close now its like he doesnt want me there at all we havent seen each other in almost a month idk what else to do hes in a really bad place & ive tried everything 😔
