Maybe she sees/ senses that your DH is very happy. She may be a little bit jealous of that. Maybe she is realising the mistake she made. This may not be what you want to hear, but I would be worried if my DH acted a little "off" after getting a text like that. Thats just me though.

She sounds like the BM I deal with. We can always tell when things are rocky between BM and her BF (same scenario - she cheated, they've been divorced for 4 years) because she starts sending FH texts like your BM did. I guess when their lives are crappy they realize how THEY screwed up a good thing and WE got great guys out of it.

She realizes what all cheaters realize that the grass is not always greener on the other side just a different shade of green - I may get flamed for this but tough - if our BM ever wrote that to my husband - not only would he get an earful but she would get an earful as well. When we were first married she used to call DH to cry on his shoulder about how hard life was - really - BM cheated on DH - got really good CS the first year of divorce then shipped her son off 700 miles to live ft with us and paid no CS the first year and barely anything the next 2 - I told DH she lost the privilege of crying on your shoulder when she opened her legs to another man when she was still married to you - I said either you stop the Bullshit or I will.

She did it a few more times and DH and I were trying to get pregnant - she called one of the nights that I was ovulating and DH was on the phone with her for awhile - I was getting tired and by this point sex was about me getting pregnant - it was the 10 month of really trying to get pregnant - I went out took the phone out of his hand - said Hello BM - sorry but I need MY husband so that I can get pregnant - have a great night and call a friend if you need to cry to someone DH is off limits for that from now on (it was the night I did get pregnant!)- DH was shocked but I think secretly happy that he did not have to look like the bad guy - I did not care that I looked like a bitch this was my man now not her's. She never discussed her private life with him again - and I do monitor his phone and he knows that I do and if I see a long call from her I inquire - I don't give a shit what anyone says because if my Exhusband would be doing that with me believe me DH would not like it.

i agree with the above who stated they are just wanting what they no longer have and see what a dumbass decision they made. my DH still has exgf's texting / calling to get together like old times. they quit calling when he says ok but only if my wife can come and wants to do that with you
