Talk to him, maybe you guys can work things out.
It doesn't matter what I would do. It matters what your ex would do and you won't know by asking anyone other than him.
Sounds to me like you just needed to clear your head and refocus. Maybe he didn't understand why that also meant excluding him, but I don't see that you did any wrong. If you do love him and he didn't do anything wrong to cause the break-up, then I see nothing wrong with wanting to get back together. Perhaps now that things have settle for you, you can talk to him or send him a message explaining what was going on, that you miss him, and want to start things fresh.
What until summer time and find a nice boy and hold hands and be happy then.
That's really going to up to your ex, don't you think. You probably hurt him.<br />
You'd have to convince him that things have changed and he can trust this won't happen again.
