<human>: We were together for 2.5 years before he broke up with me because he felt uncomfortable with the age difference, telling me we were in different places in life.

I found this incredibly difficult but I accepted that's what he wanted to do. Since then we have spoken on and off and regretfully it has been me initiating contact 100% of the time. None of our conversations were about the relationship, just small talk.

A few days ago I ran into him and we went for a walk and spoke for about an hour. There was no awkwardness which surprised me, since I am very very much still in love with him.
Near the end of the conversation we spoke about the relationship which pretty much ended in a lot of hugging and me telling him I'd do anything for him but I can't just suddenly be 27 - 28.
He also said he would love to be with me but doesn't know if he can handle the differences which come with me being 23.
This whole thing ended on him telling me he would think about it, in response to getting back together.

I guess what I want to know is, is this something that can be overcome? Is he waiting for me to just get older? I have no idea what this man is thinking and I don't see the problems in the age difference he does.
Is 'thinking about it' just code for 'not going to happen'?
Someone explain this shit to me! I'm so confused about everything!

Can you summarize the given text in a few sentences?
<bot>: Old boyfriend can't handle the age difference but when we met up he'd think about getting together.... What does that mean?!
