im really sad this evening

I don't think my friend likes me anymore. he never texts me first and the only time he really shows interest in me in when I mention him in tiktoks. but now all our text messages are dry. I can never play Roblox or anything with him anymore because now he has a job and a girlfriend. I don't hav a girlfriend or a job and it makes me feel sad because I feel like he's too occupied to talk to me and he was the only friend I was talking to this summer. I don't know what to do...:(
