<human>: Give me a shortened version of the text

When i was 10 years old,my mom and i caught my dad several times cheating on her with his secretary,who was a divorced woman with a boy of my age.He didn't allow us to visit him at his office much,but when we did,he showed more care and love to that boy rather than to his own girl.

It was a  painful process.we moved to my grandparents house...My mom decided not to marry again till i grew up.She dedicated her entire life to me,in order to make me a good person.

So all those years i worked hard to make my mom proud.I graduated on top of my class,and recently graduated law school.But you see,as a teenager i didn't want a boyfriend...I've built walls around me so no one(boys) could come near me.I didn't want to get hurt nor ruin my life over a boy...After all,i was the girl whose father abandoned her over a woman,and even didn't make the effort to see me once all those years.I didn't want to get hurt even more.

Now,I've been with my boyfriend for 3 years.He has been my best friend since middle school.It took him 6 month in order to break the walls that I've built.Im sure he's the one for me,i dont want to be with anyone else.But the shadow of my dad's actions is affecting my relationship with him .My boyfriend is the most loyal person in the world but i keep on doubting him,and i always turn out to be wrong.And much other issues due to my insecurities.He was ok with all of this because he understood my problems.Until recently i feel like he's had enough with my actions which are due to my insecurities.

Many times I've decided not to let that "complex " rule me...But trust me,it keeps on appearing in my head,the idea of an unloyal and uncaring dad.

I need advices please.
<bot>: My dad abandoned me when i was 10,and haven't even bothered to ask about me...this created some insecurities in me and it's affecting my relationship with my boyfriend.
