A littlebitlost, you absolutely need to cut your EA out asap, if you want him back. Period, your emotinal support should come from your family and spouse.
Use this barometer, do you say anything to Greg, that would upset your husband, do you or have you hid this relationship or conversations from him. If the answer is yes to either question it is wrong and will not bring anything positive to your reconciliation process.
I do not care if he is on his side, I don't buy it and it is a problem. In regards to your H. you can only control yourself. You must earn the love and trust back. You can not dictate who his friends are. So if you don't like it, don't stand for it. If you stand for your marriage you need to dump the EA, and obey the principles.
Prayers for your family and the young Kids, I hope for the best.
