Well, I’d be careful about jumping straight back into a relationship with him.
Perhaps the time apart has made him realise that what he had with you was special, but it could be that he’s just missing other things like sex and friendship, and he hasn’t met anyone else.
He needs to prove to you that he’s serious so, if you still love him and you do want to try again, then take it slowly and make sure you both want the same things.
You don’t say how you feel about this new relationship. It might be worth thinking about how that could develop and giving it a proper chance.
