My DP and I have been together 3.5 years..
I knew his email address was his ex wives name. Its her first name and her maiden name so say it was Tracey Smith it's traysmith@shortened somewhat.
I happened to mention it to him as it was bugging me slightly. She has been very abusive and up until recently text him and phoned him constantly.
He explained that initially he had set it up with her together (he wasn't allowed his own) then eventually she got a new address and he kept the old one. He has had it for ages and he's thought nothing of it and it would be a real hassle to change it.
I can see why he wouldn't give it much thought I just think it's a bit odd.
He then said but you've not changed Yr name. I'm not divorced yet and I want to keep the same name as my children unless of cause my DP and I decide to get married.
He did offer to change his email address but it is alot of hassle. I couldn't imagine keeping my ex husbands name and surname for an e mail address I'd want my own name. Why not?
