After 45 days of no contact, my ex doesn't reply my text

My ex and I were in a long distance relationship for almost 2 years. Everything went well for the first year but as time went by we paid less effort in our relationship. I guess it was one of the reasons why he said he didn’t love me anymore when he came back to our city in June. And I know my insecurity also messed up our relationship.

He asked for a breakup in July, i.e. after he was back for a month. And then he left again. I only texted him twice during the first month of our breakup but I either received no response or a rather negative response. So I started my no contact.

After 45 days of no contact (and now he is back), I text him to say that he left something in my place but he does not reply my text.

What should be my next step?

Sadly that means more no contact. You really can not do anything else because anything else will look desperate.
