can i win my aries man back? (with libra rising, aquarius moon)

I am a gemini woman (moon in libra, rising in aquarius) We dated for a year and a half and recently broke up. The issues we were having were revolved around me not meeting his needs and not acting on it when he has brought it up in the past. I admit - it was a massive mistake on my part for not responding the right way but this was mostly due to my own personal issues holding me back.

I have come back to my parents for a couple weeks so we have some space from each other (I'm a student and have been living with him since may) I wrote him a letter the first day I was here basically pouring my heart out and idk if I should warn him and tell him not to read it or if I should just not say anything and see what happens lol.

We have been speaking everyday since and I have been reflecting a lot on these issues. Everyday has been an improvement for me so far. He says in a few months from now if he can really sees the improvement there is a possibility. Is this a realistic timeline? We speak as though we're still together and he tells me he loves me and misses me but I'm unsure if I'm giving myself false hope and he just wants to be friends. We are still very in love but there is a lot of doubt coming from his end and he is very adamant about the fact we are broken up. He says I have a lot to work on and that it takes time.

Should I be harder to reach than before? Should I completely cut him out and try and move on?

I know what needs to be done and I'm taking the necessary steps to do so because I still see a bright future for us. I'm just inpatient and finding this situation hard to manage.

HELP!

Which of his needs are you not meeting?
