Friend showing romantic interest in me suddenly asking about past relationships and talking about not being stable to be in one?

So male friend who flirts a lot we talk on the phone a lot (doesn’t live near me) tonight was asking me all about how long I’d been single for and why and many questions. He then started talking about him needing a proper job before being able to commit and his ex girlfriend wanting too much too soon etc and we had a deep conversation about this and suddenly from him being very affectionate it felt like I’d been friend zoned … what’s the deal?

Hmm so he’s literally come on stronger since this happened and I left him to it for a few days then after a few days he contacted me and he has seriously escalated it from there!!
