I could have written this post myself 25 years ago. Met a guy and we hit it off immediately. Things moved pretty fast with us and we both became really keen on each other quickly and I could really see it going somewhere. After a while the 'ex's' conversation came up and he was honest with me in saying he worked with his ex. They worked in a small office and there were only 6 of them in the team and she was one of them.
I tried to be cool about it and pretend like it didn't bother me but it did. I can't really quite put my finger on why it did but I had these awful feelings of insecurity.
This ex was a fairly long term relationship of a couple of years. They went on holidays together and got on with each others families etc. He reassured me that they were over and that he was the one that ended it but they were amicable and friendly with one another as they worked together, but that was it, but I still felt very weird about it all.
Fast forward to his works Christmas do and I obviously got invited to go with him. When I met her in person I felt 100 times worse. Not only was she a few years younger than me, she was naturally REALLY gorgeous with massive boobs.
This led to massive feelings of insecurity and it was a massive knock to my self esteem. I spent months thinking why is he with me? And that he had a massive downgrade. He never gave me any reason not to trust him or to think that he still wanted to be with her. He told me he loved me not long after that Christmas party and that he wanted to be with me.
I eventually told him my feelings of insecurity and we talked it through. Turned out he felt exactly the same about my ex husband. My ex was a good looking man. Typical tall, dark and handsome where my new guy was shorter and not as conventionally good looking as my ex, although he has always been gorgeous to me.
Those feelings of insecurity about our exes disappeared once we actually sat down and talked it through and were really open and honest with one another. Suddenly I stopped seeing her as a threat to our relationship.
Hopefully, if he is worth it, you will find you will get past this, as your relationship strengthens, but I will encourage you to try and think rationally about things. My fella always used to say if he wanted to be with her he could. She is his ex for a reason.
My guy and I married and have been married now for 20 years. Happily. So please try not to let your insecurity ruin something that could be amazing.
