Why did my gf break up wtih me? its a blurr.?

well i was with this girl for 4 months where both 17 and we got into an argument where she was supposed to come to my house but she never came and i didnt hear nothing from her for 3 days no calls or text so i got angry and left some awfull voicemails saying **** you. and stuff well she said that she had an asthma attack and she could not call. well she comes back from the hospital and dosent call me or anything if i recall i had to call her and it was over... and know i dont know if shes carrying my baby when we where together she got really jealouse was a very controlling girl and i know it was for the better but i just cant seem to grasp why? when before we could of worked something like this out? i was nothing but nice to this girl and i know some of u guys where gonna say i was the controloing one but u guys have no idea. what i went with this girl know im hearing shes talking about our personsal life in school and stuff. and another thing those 4 months her mom didnt know nothing about us and she said that if her mom found out she would prob kick her out the house but its hard for me i loved her and i know she wasent the one for me but its hard so know the question i ask? is i should go ahead and confront her mom even if she dosent want me to? she said she was preg but for what i ve saw shes a lier but i did *** inside of her a couple times so its a possibily im confused i need ur guys help!! plz!!!!!!!!!!!!!!!!
