Need help to get over the fact that my girlfriend got an ex boyfriend

[JCVD]

Hi, sorry for my bad english in advance.

I’m with my girlfriend since 6 month, we know each other since we are in middle school. After that she go in another school and in an other high school in the same town.
We are now both 20 years old, we started to speak together after all these years via facebook and we date some days after, she told me that she had 1 boyfriend during her last year of high school and it lasted 6 month, she lost her virginity with him and i appreciate a lot her honesty.

Now we love each other a lot, I see all my futur with her and for no reason i can break up, that’s the same for her.
At first the fact that she was no more virgin didn’t bother me at all ( I do not care if a girl is a virgin or non virgin ).

But the problem is that 3 month after we started this relationship i really fell in love with her and started thinking about her doing her first time with her ex boyfriend and a lot of more bad things. I was thinking that it’ll go outside my head with time ( i tried to no give matter to it ), but the fact is that the days passed and i was thinking more and more about it, i kept everything for me after 1 month of struggle i’ve decided to tell her what was going on.

I told her that i was thinking about all this and that it was bothered me since 1 month.
She answered me that she regret to have done her first time and to have be with him and that she is very sad about it, she didn’t know why she did this ( I think it’s because like a lot of people now she wanted to lose her virginity as soon as possible,specially at 20 years old and i understand this ).

It was during her last year in high school and he was in her class, she told me this is the thing that she regret the most in her life and if she could go back in times she would only change this, she told me that she was just attached to him and that she saw him only during class, that she slept only around 10 times with him and after 6 month he left her she said that she didn’t think about him one time since she is with me, that he is an and that she have forgot him with no difficulty ( I’m aware that i’m young, that it’s all my problem and that it’s all in my mind, and certainly not her problem ).

She said that she discovered the real love with me and that she love me more than everythings.
After this conversation i didn’t speak again about it with her because i don’t want, some days after, i spoke with her mom about this ( i know her since 10 years ) and she told me that my girlfriend wanted to see me and date me for years and that she was speaking about me everytimes, that i was in her mind everytime and that she never thought being with me one day.

The last thing i regret the most is that i come 6 months to late because she wouldn’t met this guy.( and i know that 100% of people in this world regret things in their life and that the majority would preserve himself/herself for the love of their life ).
I’m aware that there are a lot of worst thing in this world and i do my best everydays to get over it but i can’t and it’s hurting me everytime i think about it, and trust me i think a lot about this. I feel like i’m blocked because i can’t leave her but i can’t go back in time to change that, the only thing i can do is to accept it but i don’t even know if it’s possible
Is there any people who had nearly the same problem ?

How can i work on myself to accept this and stop hurting me with these thoughts ?

Thank to everybody who have read this and who try to help me and sorry again for this bad english.

I had the same problem when i was younger. Get over it, its not a big deal. If i found a girl these days who only slept with 1 guy it b the same as finding Virgin Mary. These days there are15 year olds already slept with 10 guys.
