Tamia,
The only way that the lender will remove your name from the mortgage is if your ex partner has the income to take the mortgage over on a sole basis. i.e can the amount borrowed be sustained with his salary alone (as per the lending criteria of the bank)! I have been in this situation and I'm afraid that this is not a quick process. You don't need a solicitor to arrange this but obviously your partner is stalling so you must speak to a solicitor asap! Good luck!
