Are the past relationship with the men in my life making me sabatoge or hinder my relationship ?

my relationship with my bf isnt that gr8 but we r both tryin 2 hold on. i am 6 mth preggers so my emotions & hormone r runnin super high besides that the first man that i remember bein in my life was 1 of my brothers. he was like a knight. he protected me helped me gave me validation but all that ended when he died when i was 3. after that i wasnt protected my other brothers made me feel ugly stupid & my older nephew molested me when i was around 4. throughout the yrs i didnt really have long lasting relatioships due 2 the fact i wasnt giving my self up. i stayed a virgin til i was 21 & gave my virginity 2 my current bf. my father really wasnt in my life until i was a jr in hs we got close had a good bond but during the time i was getting my relationship with my bf my father ped. i ended up feeling alone cuz my bf really wasnt there the way i needed him 2 be. now he is the main man in my life bt the issues r stressin plus he has major issues that he surpresses & i end up on the receivin end of the stick.
