LE - I hear you buddy, I miss my boys terribly, but you need to move on for you and try and accept, although this isn't your fault or your doing, you get the time you get so don't waste a single second of that time. It's precious time and all you've got right now so just enjoy it.
I also hate the exchanges too, I don't get those conversations, but generally a bit of grief in some format. Let her know about their time, ask about any activities coming up I should know of and then I get out ASAP. I don't want to know any of her business and unfortunately, due to small town syndrom I do find out little bits and they throw the old brain a bit so I'm with you. Best not to know.
I'm not sure you can reply to that text without sounding, desperate, nasty, or just babbling so I personally would avoid it. Anytime I get a non kids related texts or question type text, I ignore it. As someone said above, they are trying to make themselves feel better as they now see it's the kids who are really hurt in all this.
