I have a totally different opinion. Here it is.
If he wants to get back with his ex he can do it no matter what (wether he's married to another woman or not, wether he has children or not). Just give a good look around: there are people with 3 children that for love (or sometimes for lust) leave their family. So the family card is not one to play. Read carefully:
1)trust him and let him do his thing, if you tell him not to he'll do it anyway without letting you know which is worse;
2)Start to get involved in new activities outside your home and tell him about it (you'll distract yourself from focusing too much on him and will give him the feeling that he is not stuck with a needy woman - he is with you because he wants to, not because he has to - same thing goes for you);
3)Don't tell him not to do things that he cares for, being in a relationship does not mean limiting the other, but rather making him/her be himself/herself. If he screws up and leaves you don't loose much, he was not 100% committed to you in the first place and you deserve better.
4)Nobody wants to feel in chains, every now and then mention her to remind him that keep one eye open and, yet, you have the self-confidence to let him keep a female friend.
5) Last, but not least: get a male friend!!It's fun, refreshing for you (free handyman) and your hubby will feel a little less secure, which helps! (little tip here: get one that you actually like, just in case ;-)
I hope you don't think this is crazy...it works for me!
Good luck
