fuck.. what do I do?

Só im in a long distance relationship and I'm suffering with depression and anxiety and he knows how much I need him but he's just been so off with me... he's hiding something because when I ask him what wrong he always says good night or whatever and the past few days he hasn't said 'I love you' and if I say it to him he'll just pretend he didn't read that message.... i just don't know what to do anymore, he won't talk to me about what's going on and I just feel so lonely, been missing college and I feel like the only person I've got doesn't want me

Anymore😞😭
