Called my girlfriend the wrong name
I called my girlfriend by the ex wifes name. We have been together for 4 years and living together for almost 2 years. It happened on the day of my Dad's funeral, I had a few to drink and was pretty emotional, Iwas talking to my sister asking where my girlfriend was but mistakenly used my exs name. My girlfriend heard me say this and got very upset. I have no idea why I said it, and I am now very contious about it every day. I now worry that i will do it again, because I dont understand how I did it the last time. Its driving me crazy.
I have no feelings at all for my ex-wife, I love my girlfriend to bits. She is everything to me, but she is now threatening to leave me if i do it again.
I keep apologizing in every way I can think of but she will not accept it. She now believes I still want my ex and that I no longer love her. Its driving me crazy and driving us apart.
This is now 2 months ago since it happened, my relationship is on the rocks. I wish it never happened and that i never hurt my girlfriend, but I fear its too late for us.
Any advice is welcome.
Thanks
