Funding as a newly graduated PhD
Firstly, congratulations on finishing! It's a big achievement. 

If I were you I would be applying for post-doc positions and/or industry positions ASAP. It depends on whether you want to stay in academia or work in industry. 

Think about what you want to do and don't get misled by your ex-advisors mixed messages - if he really wanted to continue working with you, he would help you find funding instead of leaving it all up to you. If you really are interested in staying with him then ask him if he could give you advice on what funding you can apply for as newly graduated PhD.
