Search Results: ex wants to work things out

Hi, I'm looking for some advice please 😊 I have recently broken up with my now ex boyfriend, due to a gambling problem, drinking issue, questioning my worth, financial issues and his negative attitudes and behaviours. He wanted me back and is saying he will make changes, I know he has quit gambling, not drinking as much and he's saying all the things I want to hear and have in my future and would do anything to have me back and saying it's me or no one.
I've been asking for the last 5 weeks since we broke up to give me space so I can decide if I miss him, he can implement these changes he is speaking of and I can have some alone time to decide if I do really miss him and want to try again. Thoughout these 5 weeks he has smoothered me, begging to take him back and telling me there is no one else, he will never date again, he wants to marry me, have a family and will support me and be a better person. he's even offered relationship counselling and said he will do anything to make it work.
Two days ago I said no let's call it a day I'm done I'm not willing to give it another go, his pushing for an answer was exhausting and it's was pushed me to say no I'm done. He has then done everything I asked yesterday stopped the messaging and then sent a quick one this morning to say he'd removed me from social media not to be petty or vindictive but for his own mental health. Since he's done that, I regret it he's never left my head, I can't stop crying and I feel sick. What should I do?
