Why is he ghosting when he was literally asking to meet my parents?

This boy and I have been together pretty on off for close to 4 years. Recently he started talking about how he wants to meet my family and how he wants me to meet his. We had a small convention about it and I told him I'm not ready then he said we'd never be ready it'd just a leap we'd take. Literally since then he's ghosted me for a full week now and I'm genuinely so frustrated. I'm starting to think he might be mentally ill.

This sem more especially we've barely spent time together because we were supposed to be on a break but we realized breaks don't work and he told me that the only way he sees us ending is in marriage right. He tells me he loves me constantly when we're together and always talks about marriage ams starting a family but his actions are so confusing. I'm not really bothered about not spending too much time bc I feel we are growing separately which is needed but I genuinely just moss hanging out with him all rhe time like we used to. He acts like he doesn't know what he wants and ignores me but then he'll get really drunk and go on and on about how I'm his soulmate and he's been in love with me since our first year.

He'll day all these things just to not do anything about it. I love him genuinely so much it hurts I see him in everything I dream about him constantly I just don't understand how he claims to love me too and just be okay with not talking for a week. It's so frustrating genuinely especially that he's the one who brought up our families meeting in the first place. I know we have the capacity to genuinely be healthy and stable and grow together but he's just so infuriating and I'm just so hurt and annoyed. My friends think he may just be mentally ill and I'm sick of always not knowing where I stand with him
