Are the past relationships i had with different men in my life unknowingly making me sabatoge my relationship?

I am 6 months pregnant and my hormones and emotions are on high alert. My boyfriend and i are having issuses within our rrelationship but we are trying to work things out. We both have individual problems we need to deal with and i am going forward and taking some action trying to deal with mine. One issue that i am kind of looking into is the past relationships i had with the men in my life. I am trying to figure out if maybe that is contributing to the way i feel about my boyfriend now. The first man i ever knew in my life was one of my older brothers. He was one of 3 brothers i have. He was everyones favorite and as i said before the first man i knew. He took on tghe role as my protecter, provider, caregiver, he made me feel pretty, he was my teacher, and doctor. He was basically like my dad. I remember him and i smile. The reason why i love shirley temple is because of him. I remember getting up everyday and he putting on shirley temple for me. All that changed when i was 3 years old. He ped away thats the first time i seen death. I even remember seeing him in his coffon and someone lifting me up to see him. After he died things change. My other 2 older brothers were in my life but were moreso absent because of corse they had their lives. When i did see them i was basically belittled. I was told i was pretty but they always picked at how i could change this and that. I was smart but i wasnt smart enough. It seemed as if i just wasnt good enough. This went on from when i was five years old even up til now. I have clashed with them even letting them know how they have hurt me. They were not the best male figures. I think the reaon why i resent my brother who is younger of the two is beause when i was about 4 years old my older nephew basically made me do ual things and my borther walked in becuase he was suppose to watch us and he basically said yall dont be doing that no more. I lived with my nephew for 10 years after that. My other brother likes to manipulate people with words and he has been the biggest reason why i strive to be something. Throughout the years my relationships havent been successful. All the guys i have dated knew i was a virgin and said they would respect that but in the end they just wanted . I stayed a virgin til i was 21 years old. I gave my virginity to my now boyfriend/baby daddy. When we was starting our realtionship my father had cancer. My father and i never really had a relationship until i was 16 years old and we really started to bond as father and daughter. He took the role of a great father for 5 years and made me fell like my older brother did when i was younger. But my father ped as me and my boyfriend was trying to get our relationship on track and i felt like after my father died my boyfriend wasnt there. His death took a tole on me and my boyfriend would stray away from me when i needed him. He has issues major issues that he surpresses and thens displaces all his anger on me. I know he loves me but he sometimes treats me like my brothers. It makes me feel like **** and when we argue i tend to walk away solely because this is stressing me out arguing with him and also he just doesnt listen to me. Are my past relationship with my brothers and past relationships making me wanna run from him. He doesnt make me feel secure, loved, nor protected.SORRY SO LONG
