I don't think there is any problem with dating an ex, as long as you've worked out whatever issues caused you to break up in the first place. My current boyfriend and I broke up in the past due to external problems rather than problems with our relationship, but we've now been dating for four years straight. So it can definitely work, and since your breakup was the result of someone else and not because of any issues with the relationship, I think you guys can definitely make it work.

However, I do think that there might be issues caused by getting into the relationship so soon. For starters, you said he only just broke up with his girlfriend and only because she is moving away. But does he still have feelings for her? Is there the possibility that they will want to get back together in the future? And do you still have feelings for your ex-girlfriend? Have you truly moved on from that relationship?

If you've both truthfully moved on from your previous relationships, then that's fine. But if there are still lingering feelings for either of your exes, then I do think that could cause some serious problems in the relationship. I'm not saying that it can't work, but I just think it's important for you to both consider how you feel about your previous relationships.
